Describe the Bug

Environment info.
node: 20.18.0
next.js: 14.2.22

I wanted to deploy the next.js + TS project on vercel, but I got this error.
TypeError: Cannot create property 'digest' on string 'Something went wrong!'

My project is using app router.
It occurs in app/product/[id]/error.tsx

The code is as following.

`'use client';

import Button from '@mui/material/Button';
import Container from '@mui/material/Container';

import { paths } from 'src/routes/paths';
import { RouterLink } from 'src/routes/components';

import { Iconify } from 'src/components/iconify';
import { EmptyContent } from 'src/components/empty-content';

// ----------------------------------------------------------------------

export default function Error({
  error,
  reset,
}: {
  error: Error & { digest?: string };
  reset: () => void;
}) {
  return (
    <Container sx={{ mt: 5, mb: 10 }}>
      <EmptyContent
        filled
        title="Product not found!"
        action={
          <Button
            component={RouterLink}
            href={paths.product.root}
            startIcon={<Iconify width={16} icon="eva:arrow-ios-back-fill" />}
            sx={{ mt: 3 }}
          >
            Back to list
          </Button>
        }
        sx={{ py: 10 }}
      />
    </Container>
  );
}`

On local env, there is no bug, but on deployment, this issue occured.

Please help to fix this issue.
Thanks.

Please add a reproduction in order for us to be able to investigate.

Depending on the quality of reproduction steps, this issue may be closed if no reproduction is provided.

Why was this issue marked with the invalid-reproduction label?

To be able to investigate, we need access to a reproduction to identify what triggered the issue. We prefer a link to a public GitHub repository created with create-payload-app@latest -t blank or a forked/branched version of this repository with tests added (more info in the reproduction-guide).

To make sure the issue is resolved as quickly as possible, please make sure that the reproduction is as minimal as possible. This means that you should remove unnecessary code, files, and dependencies that do not contribute to the issue. Ensure your reproduction does not depend on secrets, 3rd party registries, private dependencies, or any other data that cannot be made public. Avoid a reproduction including a whole monorepo (unless relevant to the issue). The easier it is to reproduce the issue, the quicker we can help.

Please test your reproduction against the latest version of Payload to make sure your issue has not already been fixed.

I added a link, why was it still marked?

Ensure the link is pointing to a codebase that is accessible (e.g. not a private repository). "example.com", "n/a", "will add later", etc. are not acceptable links -- we need to see a public codebase. See the above section for accepted links.
