Intermittent error on Postgres Memory

I’ve upgraded to the latest version (self-hosted) - and I’ve started get intermittent issues with Postgres Memory where the workflow errors out with “Received tool input did not match expected schema” which literally happens 1 in n executions but with no real pattern. Does anyone else have any thoughts on what could be causing this…
