Cannot load form on Enketo Express

I'm trying to load forms to enketo express from an open rosa server I'm working on but i can't get the form to load

This is the logged error

I can confirm it successfully downloads the form from the server so i'm not sure why it errs on the UI. Any ideas?

Could you try with a formID without blanks in the name (settings, file name), please. You can test it with a clone.

Thanks for the suggestion @wroos, I actually found the bug in my server, i was returning the contents of the form instead of the form list filtered by the form id i pass which is mysurvey in this case
