Description
This PR updates the resource check login in
packages/gatsby/cache-dir/loader.jsto include thepathPrefixwhen resolving resources. Without this, sites configured with a custompathPrefixcould trigger 404 errors and React crashes during client-side navigation.Documentation
This change does not affect public APIs or require new documentation. It simply ensures correct path handling in existing resource resolution logic.
