Out middleware (TicketService) uses the HTTP API to get case and ticket details based on a case ID and since we upgraded we are now seeing the following in the error message and no ticket details are returned to the middleware.

We've seen "Unable to access lob stream" before in other apps when code inappropriately handles autocommit in postgresql. We've disabled autocommit on postgresql but that made no difference to finding a resolution. Has anyone else ever experienced this issue?

Hello
could you please tell us what is the postgres database version you are using?
don't you see any engine logs related to the issue?
