[V3] findByID error on media collection in beforeValidate hook

[JeffreyArts]

Describe the Bug

Not 100% certain if this is a bug, or if it is something that I missed (or is missing) in the migration guide. But after migrating from V2 to V3, I noticed that I no longer could save my pages. I have been able to isolate the bug and put that in a repo for you to reproduce. In short;

The following code

hooks: {
    beforeValidate: [
        async ({data}) => {
            const res = await payload.findByID({
                collection: "media",
                id: data.blocks[0].id,
            })
        }
    ]
},

Will throw the following error

ERROR: The collection with slug media can't be found. Find By ID Operation.

err: {
    "type": "APIError",
    "message": "The collection with slug media can't be found. Find By ID Operation.",
    "data": null,
    "isOperational": true,
    "isPublic": false,
    "status": 500,
    "name": "APIError"
}

Reproduction Steps

2. Add an entry to the demo collection, and add 1 block that relates to the image
3. A Something went wrong error will occur in the UI and the entry won't save ( The collection with slug media can't be found. Find By ID Operation will be thrown in the CLI)

The hook should have req, and you should use req.payload.findByID. Can you try that?

[JeffreyArts]

That resolves it.

Just for my understanding. Is that because in V2, payload was initiated as a global object? By which I mean that the payload object that you import from node_modules got configured/modified, but in V3 this is no longer the case. When I import payload in V3, it always retrieves the "clean", "untouched", "fresh" payload object?

The hook should have req, and you should use req.payload.findByID. Can you try that?

FYI: Had to use req in a FieldLabelServerComponent's. Importing payload direct threw the same error as @JeffreyArts

const UseAsLabel: CheckboxFieldLabelServerComponent = async ({ req, siblingData }) => {
  const result = await req.payload.find({
    collection: 'posts
    where: {
      id: {
        equals: siblingData.post
      }
    }
  })
   
  return `Hey`
}

export default UseAsLabel

any update?

Just use payload on the req and do not import payload directly.
