"Client-side databinding failed" on Instance File Manager

Hi, I'm encountering an error while trying to use this. Everything works fine, except for the File Manager inside of an instance. The global file manager works just fine.

Client-side databinding failed. If you've just upgraded AMP then you should first try clearing your browser cache.
