Hi, I'm trying to update our Wallaby cloud to Xena. Doing this for Barbican and Heat, I have a problem when trying to upgrade the database. Here is the log for Barbican: ---------- [root@os-77023 ~]# barbican-manage db upgrade head [root@os-77023 ~]# barbican-manage db current ERROR: 'int' object is not iterable [root@os-77023 ~]# barbican-manage db upgrade ERROR: 'int' object is not iterable ---------- I can find a similar error in log files of Heat services, for example in heat-engine.log: --------- 2024-03-05 12:16:27.978 1638283 INFO heat.engine.worker [-] Starting engine_worker (1.4) in engine 686dc841-d595-49cd-bf5e-04a4de876dc1. 2024-03-05 12:16:28.109 1638283 ERROR oslo_service.service [req-b991252a-f4c1-4955-a2ed-b20db59a161c - - - - -] Error starting thread.: TypeError: 'int' object is not iterable --------- My DB connection information, working well with Wallaby, is: ---------- sql_connection=mysql+pymysql://barbican:very_secret_pwd@os-sql-admin.lal.in2p3.fr/barbican ---------- I cannot find any other useful information. Anything trivial I missed? Thanks in advance for any help. Best regards, Michel
