Hi @bjornnorlen
Thank you for reporting this.

I can replicate this one in v16.1.1

This happens because there is no "Allowed file upload types"
A work around is to set a allowed file upload type.

We will look at a solution a see how to best solve this

A solution could be to set it to "allow all files" as default
