Keep running into this bug with Lucee 6 (currently 6.0.3.1) re: sessions when

this.sessioncluster = true

.

lucee.runtime.type.QueryImpl; incompatible types for field recordcount

The error is thrown on the first reference to anything in the session scope. Anecdotally, this appears to happen when switching between Lucee 5.4 and Lucee 6 servers, after a time the session gets corrupted and won't write back to the server without throwing a sql error. (SQL Server 2019) Additionally, Application.cfc appears to be cached and only after restarting Lucee entirely do changes to Application.cfc start getting picked up again (this may be a Lucee 6.0.3.1 issue). On top of that, the reference to session throws an error that breaks out of try/catch. So you can't trap the error and rotate the session or anything like that. It throws a hard error that can't be captured with a try/catch. The only solution? Clearing your cookies.

I would suspect you need to clear the contents of your cache

Well, we're trying to do a slow rollout to find Lucee 6 issues, so we're running on Lucee 5.4 server (in case we need to rollback) and a Lucee 6 server

right, and that ain't gonna work 🙂

Fair enough, then why is the error throwing outside of a try/catch?

So Lucee can't deserialize classes from one version of Lucee to another

Ahhh

I'd have to see the stack trace

Does the error in the stack trace appear on only in the logs, or is it what the browser sees as well?

It's dumped right to the browser.

yeah, that's an odd one-- I don't know why you can't catch that. Lucee's catch mechanism may be preventing that for some reason

Yeah, without being able to catch it, there's not much recourse. I could wipe out the CFID cookie programmatically, or maybe rotate the session, or any of a number of other possible solutions, but I can't do anything except "tell customer to clear their cookies" and instead of a friendly error page it shows a Lucee dump

yeah, but that's always been the case

Understandable. If nothing else, I'd consider the inability to trap the error in a try/catch a bug.

I agree there. A ticket may be in order

I'm also not sure if the Application.cfc's updates failing to be picked up on request is a regression or not, or specific to this issue, but that seems like new behavior. I'll see if I can isolate that one more.
