Redmine

After migrating from redmine 3.3 to redmine 5.0.5.stable some of the projects won't show their time entries despite others.
I personally migrated the rows from the old SQL server to the new one, paying attention to the structures of the new tables. Everything else works correctly, only for a few projects I get this error:

Does anyone have any clue to solve this?
