We have one questionnaire stuck in a tablet. I have been able to transfer the data from my phone, identify the missing questionnaire. I then followed the instructions here to upload it manually through bulk upload (Manually Uploading Submissions โ KoboToolbox documentation), but I get the following error.
Can you please help?
500 Error
If this is a significant error that needs to be fixed, please send a support request to support@kobotoolbox.org with information about what triggered this error.
Welcome back to the community, @smaz! Could you make the following two checks:
Check if the project still exists on the server?
Check if the submission stuck in the device belongs to that project that is not syncing with the project (deployed in the server). In this case, a submission cannot be synced with the server.
