Yes, it was the field name. I thought the forbidden name was “video”.
But still, what is the blueprint field type for video if it isn’t a block? Can I only have a blocks field to have a video field? I couldn’t find it in the docs.
You would use a files field and limit what type of files can be uploded via a file blueprint (using the accept option (if you want to use a video file).
If you only want to use a video url, you can use a url field, that’s what’s used in the video block as well. There is no video field type.
A video embed isn’t really a file that you upload to a site, thats why I thought that would be the wrong way to do it. The files field I think of as something to upload and then present it to the user like an image or for downloading it like a PDF, but a video embed feels different to me. But maybe that’s really just me.
Aaaand more than a year later I completely forgot that ‘videos’ is a native Kirby Method, so I made the same mistake just simply again. Searched the forum and found the solution in my own question from last year. Boom, its so easy (without a brain).
