Cannot generate a link for a record without a resource. You

Error message

Cannot generate a link for a record without a resource. You must use useGetPathForRecordCallback within a ResourceContextProvider, or pass a resource parameter.

What it means

useGetPathForRecordCallback returns a callback that resolves a record's URL. Inside the callback it resolves the resource from the params, or falls back to the resource captured from the ResourceContext at hook time. When neither exists it throws, since generating a record link requires a resource name.

Solutions

1. Include resource in the callback params: getPath({ resource: 'posts', record }).
2. Call the hook (and thus capture the context resource) inside a ResourceContextProvider subtree.
3. Guard the call: only invoke the callback once the resource is known, or provide a default resource.

Example fix

// before
const getPath = useGetPathForRecordCallback();
const url = await getPath({ record }); // throws outside resource context

// after
const url = await getPath({ resource: 'posts', record });

const getPath = useGetPathForRecordCallback();
const safeGetPath = (params) =>
    (params.resource ?? resource)
        ? getPath(params)
        : undefined;
const url = await safeGetPath({ record });

const hasResourceParam = (p: { resource?: string }) => typeof p.resource === 'string' && p.resource.length > 0;

try {
    url = await getPath({ record });
} catch (e) {
    console.warn('No resource for record path', e);
    url = undefined;
}

When it happens

Trigger: Invoking the returned callback with ({ record }) and no resource in params while the hook was called outside a ResourceContextProvider; the resource prop/context being undefined at callback time (data not loaded); calling the callback on a custom page without resource context.

Common situations: Reusable row-link logic used on a dashboard; portaled components losing the ResourceContext; async handlers built at mount when context hadn't resolved; forgetting the resource key in the callback params object.
