Hi all, I am running into this error: Failed to create session: (psycopg2.errors.UndefinedColumn) column "_gbat_is_connected" of relation "otree_participant" does not exist LINE 1: Initially, I can create rooms immediately after uploading the otree file and resetting the database. However, after some time, when I attempt to reopen the room, I encounter an error. The issue is resolved every time I reset the database, but this is not a viable solution because I will be conducting a large data collection using oTree and cannot afford to reset the database repeatedly. Is there a permanent solution to fix this error without relying on database resets? Thanks so much in advance.
