Getting the same error message with the SEO plugin.

Having a typical "News" collection with a localized News image. Using the "Auto-generate" pre-fill for the image leads to it.

The only difference I see within the posted payload is:

  "meta": {
    "image": "2",
  },

instead of this when selecting the image manually from the collection within the SEO plugin:

  "meta": {
    "image": 2,
  },

So maybe this is related and just a simple typing error?

I am also getting this error for some relationship fields in the new version 3.28.1. (but had no issue in previous version 3.25.0)
