hi,
I am new here and I am trying to learn about apps. I tried for two days to use some ready-made templates, however, I get this error message. I am not sure what’s causing it.
I appreciate your help.
Had this issue a few weeks ago. Does this occur when you want to preview the template or when you try to clone it?
