An error on previewing/deploying my questionnaire

Dear Kal_Lam,

Thank you for your reply on my post.

I have decided to change the form design itself to avoid the error mentioned in my post, but now I have been struggling with previewing/deploying the updated form. Now the above-mentioned issue (Unexpected token < in JSON at position 0) does not occur but currently my survey form cannot be previewed/deployed in KoBoToolbox.

When I upload the file and go into preview, it continues to load the form for more than 10 minutes and does not show the preview. Deploying the form was also failed.

I checked the form using XLSForm Online v2.0.
It returned that the default value used in geopoint-type questions “-6.175628 106.82699” are not acceptable. I deleted it and the remaining warnings are only “Question has no label”. I suppose it is no problem if I intend to do it. Then the form could be displayed from “open in the browser”.

However, when I upload the file in KoBoToolbox, it won’t work.
I hope if you could find any issues in my form.

Please feel free if you need further confirmation on the form.
