Description

Using hikari connection pool, I am getting weird `connection is closed` error for a flow during sql updates. There is nothing wrong with the data or query as far as I can see so I am confused why I am getting this error. I have many flows but the only one with the error is this one.

Any ideas what can be causing this error?
