If you are in a rush and you’ve collected data despite the error, your best bet will be to use Briefcase to pull submissions from each device: https://docs.getodk.org/briefcase-using/#collect-directory (skip the step about finalizing forms). You can then push that data to your server.
I would recommend filing this as a bug report with Kobo. Ideally servers would not allow reuse of a form id and version combination (ODK Central does not within a project).
