The error message you are seeing:
TypeError: Cannot convert undefined or null to object
indicates that in PaymentDetails
component at the source file src_pages_extra-pages_PaymentDetails_tsx.chunk.js:735:33
, there is an attempt to perform an operation that expects an object, but the value provided is either undefined
or null
. A common operation that would cause this error is Object.keys()
, which attempts to get all the property names (keys) of an object.
Since we cannot access your source code, here is a general guide on how to troubleshoot and fix this error:
Locate the Source of Error:
The stack trace suggests the error is in the PaymentDetails
component at a specific location in your bundled code. You should start by looking at the original source code at the indicated line number (in your case around line 735).
Check for Null or Undefined:
Inspect the argument being passed to Object.keys()
or any similar object operation. Ensure that the value is actually an object and not null
or undefined
.
Default Values or:
To make your component more robust, you can incorporate default values or guard clauses in your function to handle cases when the data might not be available. For instance, you may use default empty objects {}
or conditionally call Object.keys()
only when the data is a valid object.
Example code in react that would cause this error:
const PaymentDetails = (props) => { // This line could cause the error if `props.details` is null or undefined const keys = Object.keys(props.details); // rest of your component logic return ( // JSX here ); };
To guard against this, you'd adjust your code as follows:
const PaymentDetails = (props) => { // Check if `props.details` exists and is an object before calling Object.keys() const keys = props.details ? Object.keys(props.details) : []; // rest of your component logic return ( // JSX here ); };
State Management:
If the `` or null
value comes from a state variable or context, ensure that you have correctly initialized the state and that updates to it are properly handled.
Check API or Asynchronous Data: If the object comes from an external source like an API, make sure the data is actually being loaded and set correctly. There might need to be checks or loading states to ensure that you're not trying to access properties of data that hasn't yet been fetched.
Debugging:
Use console.log()
or the browser's debugger to log out the value of the variables you are working with at points prior to the error. This will help you to identify exactly what is undefined
or null
.
After adjusting your code, test to see if the error is resolved. If it persists, you might have to double-check the logic flow of your component to make sure the data structure you are working with matches your expectations throughout the component life cycle.

export default PaymentDetails; this is the code , what are the changes can i do to fix this error ?
The error you provided earlier seems to suggest that there is an operation in the PaymentDetails
component which is expecting an object but is receiving undefined
or null
. However, based on the code snippet you provided for the PaymentDetails
component, there aren't any explicit calls to Object.keys()
or similarly risky operations visible.
Without the exact line the error references, this makes it difficult to pinpoint the exact issue. However, there are practices you can include in your code to guard against such errors. Here are general suggestions for changes or additions that can help prevent this kind of error:
lists
) you're working with is asynchronously loaded and could be undefined
or null
at any point, you should check for this before rendering your components that expect an object.if (paymentsLoading || !lists) return <EmptyReactTable />;
Check Prop Values Before Usage: If the problematic object is received via props, ensure that you validate the props before using them.
Utilize Optional Chaining: When accessing nested properties, use optional chaining?.) to avoid trying to access a property of
nullor
undefined`.
Default Empty Objects: When using state or props that are objects, consider initializing them as empty objects if that’s feasible.
For example:
const [tenantId, setTenantId] useState(tid || '');
This already uses a default empty string if tid
null
or undefined
.
However, one potential issue might be related to non-initialized states or props. Here are steps for a possible fix:
Check for null
in useMemo
Hook Dependencies: The useMemo()
which definescolumnsuses
themeas a dependency. If
themecomes from
Theme()` and for some reason isn't initialized, it might cause trouble.
const theme = useTheme(); // Ensure theme is not null or undefined before using it if (!theme) return null;
- **Initialize States Properly**: Make sure all state hooks are initialized properly. If some states depend on props passed down or derived from asynchronous data loading, they should account for `null` or `undefined`. - **Safe Access to Theme Properties**: When you access properties like `theme.palette.error.main`, ensure that `theme`, `palette`, and `` exist and are not `null`. If there's a chance that any part of this chain could be undefined, use optional chaining. - **Safe Mapping Over Arrays**: When mapping over `columns`, it assumes every column has an `accessorKey`. Ensure that this is the case or provide fallback handling for when it is not. Regarding the error stack you provided, none of the mentioned lines directly correspond to the code you’ve shared, since the error reference points to a production JavaScript bundle. The lines in your actual source file (`PaymentDetails.tsx`) are probably different due to minification and bundling. To fix the issue, you would need to correlate the line numbers from the error message to your actual source map or development build. I'd recommend you to use a source map for your production build that way you can trace the minified files back to the original source code and better locate the cause of the runtime error. Once you have the exact line, you can take specific action to resolve the issue. Remember, my suggestions are based solely on the code snippet you have provided and a general understanding of the error message. If the actual cause is in a part of the code not included in snippet, then these recommendations may need to be adjusted.
Add these changes and give the full code
Sure, I can apply the changes to bolster against potential undefined
or null
issues, but without the full context or the actual error line in this code, these are speculative fixes focused on robustness and do not address a specific identified bug. Here's your updated code with the suggested safety checks:
// ... [rest of the imports] // types import { LabelKeyObject } from 'react-c/lib/core'; import ScrollX from '../../components/ScrollX'; import ExpandingUserDetail from '../../sections/apps/customer/ExpandingUserDetail'; import { useGetPayment } from '../../api/payment'; import { PaymentList } from '../../types/payment'; function PaymentDetails() { // Initializing state with a check for the existence of localStorage item const tid = window.localStorage.getItem('TerantID') || ''; consttenantId, setTenantId] = useState(tid); { paymentsLoading, payments: lists } = useGetPayment(); const theme = useTheme(); useEffect(() => { console.log('payments',); // removes the need to log the state right after setting it // as that would log the old state due to the async nature of setState TenantId(tid); }, [tid]); // Ensure theme is valid before continuing to prevent accessing properties on null if (!theme) { return null; } constDownSM = useMediaQuery(theme.breakpoints.down('sm')); // useMemo for columns definition moved inside of PaymentDetails component since it relies on theme. // eslint-disable-next-line react-hooks/exhaustive-deps const columns = useMemo<ColumnDef<PaymentList>[]>(() [ // ... [rest of the column definitions - unchanged] ], []); if (paymentsLoading || !lists || lists.length === 0) { return <EmptyReactTable />; } ... [rest of the ReactTable component and PaymentDetails function - unchanged] return ( <> <ReactTable {... data: lists, columns, modalToggler: () => { // setOpen(!open); // Uncomment and use setOpen state handler as needed }, }} /> </> ); } default PaymentDetails;
In this revision, I've made the following changes:
tenantId
within the useEffect
hook. It's not necessary and will log the stale state value.columns
array inside the PaymentDetails
component after verifying the theme object is not null
, which is needed for theme
to be safely used in dependency array.theme
, after invokinguseTheme(), is not
nullbefore proceeding, ensuring that no properties are accessed on a
nullobject. 4 Updated the conditional rendering to check if
listsis not
nullor
undefined` and has a length before rendering the table to prevent issues with data that hasn't been loaded yet.Remember, without the ability to see the exact line where the error occurs, any changes are speculative and aimed at general robustness rather than fixing a, specific issue. After deployment, if the error persists, the stack trace should be examined alongside a source map for a more precise diagnosis.
const columns = useMemo<ColumnDef[]>(() => [ { id: 'select', header: ({ table }) => ( <IndeterminateCheckbox {...{ checked: table.getIsAllRowsSelected(), indeterminate: table.getIsSomeRowsSelected(), onChange: table.getToggleAllRowsSelectedHandler() }} /> ), fix the error of "ESLint: React Hook "useMemo" is called conditionally. React Hooks must be called in the exact same order in every component render.(react-hooks/rules-of-hooks)"
To fix the error message you're seeing, you can modify the useMemo
hook to use an optional chaining syntax with a null check before returning the array of column definitions. This ensures that the hook is only called when the PaymentList
props are not null or undefined.
Here's an updated implementation of the columns
useMemo hook:
const columns = useMemo(() => { const { PaymentList } = props; return [ { id: 'select', header: ({ table }) => ( <IndeterminateCheckbox {...{ checked: table.getIsAllRowsSelected(), indeterminate: table.getIsSomeRowsSelected(), onChange: table.getToggleAllRowsSelectedHandler() }} /> ), // Add this null check to ensure the hook is only called when PaymentList is not null/undefined // (react-hooks/rules-of-hooks: require exact order of hook calls) {!PaymentList && return undefined} }, // ... [rest of the column definitions] ]; }, [props.PaymentList]);
By using the optional chaining syntax ?|Աץ escolhido
, the hook is only called when PaymentList
is not null or undefined. This fixes the error message related to React Hooks being called conditionally and ensures that the `columns array is only computed when necessary.
