Problem with JavaRosa parsing form

I have this problem
Please help

Org.opendatakit.aggregate.exception.ODKIncompleteSubmissionData :Javarosa failed to construct a formDef. Is this an XForm definition?

It sounds like you are uploading something that is not an XForm to Aggregate? Aggregate reached end-of-life status on May 2021 and is no longer being updated. Please use ODK Central instead.

If perhaps you are using Briefcase, then your post does not contain enough information anyone to help.

  1. What version are you using?
