after create hook not finding document (payload beta.39)

For my Stories collection, text-to-speech is generated in a hook after creation.

When deployed on Vercel,

throws a 404.

holds valid values. However, the update method apparently does not find the newly created document. I've also tested

for the new document, which also throws a 404. If I search for another Id, it works 🤷‍♂️

Any ideas or working examples how to update a fresh document?

import type { CollectionConfig } from 'payload/types'

export const Stories: CollectionConfig = {
  slug: 'stories',
  admin: {
    useAsTitle: 'title',
  },
  access: {
    create: () => true,
    update: () => true,
  },
  fields: [
    {
      name: 'title',
      type: 'text',
      required: true,
    },
    {
      name: 'storyText',
      type: 'textarea'
    },
    {
      name: 'audio',
      type: 'upload',
      relationTo: 'audio'
    }
  ],
  hooks: {
    afterOperation: [
      async ({
        args,
        operation,
        req,
        result,
      }) => {
        if (operation !== "create") return result;

        
        // [... generate audio and make formData ...]


        const audioCollectionResponse = await fetch(audioEndpointUrl, {
          method: 'POST',
          body: formData,
        });

        const data = await audioCollectionResponse.json();
        const audioId = data.doc.id;
        const storyId = result.id;

        const updateOptions = {
          collection: 'stories',
          id: storyId,
          data: {
            audio: audioId,
          },
        };

        const updateResponse = await req.payload.update(updateOptions);

        return result;
      }
    ]
  }
}

Here's the Vercel Log:

after create hook not finding document (payload beta.39)

Bumped version to beta.39

This did not change anything.

Exactly this was it. Solved, thanks! 💚
