Hi, I came across in that ussue. Do you know how to sort out that?

In that task it looks like you have a file upload field with a default value. It is complaining that the type for the default value provided is not "Folder". Make sure the default value is not a Text or something similar.

How can I set the default value!! This problem is very strange because it hasn't always happend it !!!

Please refer to the attached screenshot in the forms designer
