SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'project' cannot be null

I agree with @cilefen, that we need to know how to reproduce this so we can add suitable test coverage.

Since we need more information to move forward with this issue, I am setting the status to Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to our policies.

Thanks!
