Error 400 when editing completed surveys

We are currently facing an issue while working on editing our survey submissions by redeploying the form and resubmitting updated data. Initially, it worked successfully for two submissions. However, after that, we started receiving the following error message:


“Data server did not accept data. Contact the survey administrator please. (400)”

We have double-checked the form structure and the data format, and we haven’t made any significant changes that would explain this error. Unfortunately, this issue is now preventing us from editing or updating any further submissions.

Could anyone please help us understand what might be causing this error and how to resolve it?

Thanks in advance for your support!
