Describe the Bug

export const Courses: CollectionConfig = {
  slug: 'courses',
  admin: {
    useAsTitle: 'name',
  },
  access: {
    read: ({ req, id, data }) => {
      const user = req.user
      console.log(id , data) // both are logged as undefined

      if (user?.collection === 'users' && user.courses) {
        if (user.courses && user.courses.includes(String(id))) return true
      }
      return false //this always returns false because the id is undefied
    },
  },

  fields: [
    {
      name: 'name',
      label: 'Nume',
      required: true,
      type: 'text',
    },
  ],
}

I have a Users collection that have a relationship to this Courses collection and I need to check if the user has the fetched course included in the relationship.

But in the access read function the id and data of the document always return undefined, I also saw some other people having the same issue on discord.

Reproduction Steps

Create a collection and log the id and data parameters to the console.

export const CollectionName: CollectionConfig = {
  slug: 'collectionSlug',
  admin: {
    useAsTitle: 'test',
  },
  access: {
    read: ({ id, data }) => {
      console.log(id , data) // both are logged as undefined
      return true
    },
  },

  fields: [
    {
      name: 'test',
      label: 'test',
      required: true,
      type: 'text',
    },
  ],
}

As per the docs, only the following arguments are provided to the read function: req and id, but data appears to be also there.

On the same beta as yours, this:

access: {
  read: ({ id, data }) => {
    console.log(id, data)
    return true
  }
}

Results in undefined undefined when I'm in the collections view and then it's not undefined (it logs the id and data) when I open a single document. This is expected behaviour. Are you getting undefined when you open the document as well?

Have you tried using a Where query instead of returning a boolean? Something like:

read: ({ req: { user } }) => {
  return {
    id: {
      in: user?.courses,
    },
  }
}

Then in your Users collection, the relationship field courses needs to have hasMany: true and maxDepth: 0 as to make the user.courses an array of IDs.
