I have the same issue could you help me plz

Unexpected token < in JSON at position 0

I have this issue

I have tested this website ODK - XLSForm Online v2.x and there is no error

Welcome back to the community, @ammaar_al_nofaish! Would you mind trying it out with Collect android app and see if the issue is seen there too?

with KOBO app is very well but I want to use the Google Chrome page to collect data

@ammaar_al_nofaish, I see that you have a very long list of choices. Hence this is taking a very long time to load all the choices. Please be informed that the web server only allows each request to take 120 seconds. And if a form is not able to load even within this 120 seconds your forms do not get deployed.

You could thus solve this by either trying to collect your data through Collect android app or build your survey project using an external select.
