Error: Failed to load data

Dears KoBo community,

I am deploying a new form. when I open the form on the web I have this error message

And I get issue in The status of my survey as follows:

  1. Works on Android Collect (Yes, working fine )
  2. Works on preview (web browser)? (Not working)
  3. Works on the Enketo webform? (Yes, working fine)
  4. The form deployment (Yes, deployed fine)

Meanwhile, the form is working fine in the KoBo toolbox android.
Please give me advise. ASAP

Welcome to the community, @Febriyanza! Maybe you could also validate your xlsform through this online validator to see if there are any syntax issues.
