Error 400 when submitting form: "Data server did not accept the record

Hello Kobo Team,

I am encountering an issue while submitting a form via Enketo. The error message says:

“Submission Failed – Data server did not accept the record. Please contact the survey administrator. (400)”

This happens only with some records. If I re-enter the same data and submit again, sometimes it works.

Could you please explain what this 400 error means in KoboToolbox?
Is there anything I can check or fix in the form or data to prevent this from happening?

I’m using Enketo through KoboToolbox.

Thank you in advance for your help!

Kind regards,
Sheranie Kharpatoe

Hi Kalyan, I’m experiencing the same issue. It’s weird that I see this error in one form but not others. Is this a Kobo site-wide issue or just for certain accounts/projects?
