Postgres RDS Aurora switchover failure

Question

I have an RDS Aurora Postgres cluster on version 13, with a blue/green deployment on version 16. When trying to do a switchover, I'm getting the following error: "Switchover from DB cluster my-cluster to my-cluster-bluegreen-a6dufr was cancelled because there are DDL or Large Object changes on my-cluster that can’t be replicated. Delete the blue/green deployment along with the target cluster, then re-create it."

I tried recreating it as suggested, but got the same error again. I'm not running any other DDL changes at the moment, and I'm not sure what to do. Any guidance on where to look for more details?

It is not entirely clear what the issue is. But you need to understand that for postgres based blue green deployments you cannot do any DDL statements during the period when you create the blue green deployment until you complete the switchover to green.
