Platform not specifying errors in my document

I'm trying to upload a file, but it says that it contains some errors. But it doesn't point out those errors.

Hi Mateus,

Yes, the import isn't good for telling you what's wrong.

Quickly looking at your screenshot I would say the URL field is causing the issue. It's not a Prismic field, you can see this is the import reference. The UID is what is used as your URL:

Thanks.

Hi Mateus,

My colleague has pointed out the URL field is probably a Key Text field and not the issue.

They also suggested checking your media imports. You, unfortunately, can't import anything into a Media Link field (other than an image), so this might be the problem.

Thanks.
