0 Unknown fetch type '8' for View My Profile menu item in Gantry Helium

This error happens in Joomla 4.2.4 when trying to view my own profile either via the menu selection or from the CB Login Module.

0 Unknown fetch type '8'

I just migrated this site from 3.10 to 4.2.4 and even reinstalled CB afterwards. I am not sure if this is an issue with CB, Joomla, or the Gantry Helium template, but it did not happen on another site I migrated earlier this week that uses the Hydrogen template. So I switched this site's template to Hydrogen. Same issue. Then to Cassiopeia. Ditto. I even tried just appending the following to the site URL and it did the same thing.

Not sure what to try next. Thanks in advance for suggestions.

CB version 2.7.4+build.2022.10.21.15.41.28.56bdcdeab

Very weird. This has magically repaired itself. But now I am having a similar issue with Phoca Downloads. It cannot get to the categories via the links it created itself. Is this some new J4 issue or something? It seems to be playing whack-a-mole with me.

The below open issue is the only thing I could find regarding it.

Within Joomla global settings under Server what is "Database Type" set to?

Issue seams like a problem in Joomla though and nothing we can directly do anything about. We're barely using Joomla APIs as is so it's unlikely core CB or any of our products would throw this and more likely it's a 3rd party extension or 3rd party CB plugin installed throwing it. I suggest going through your entire install and being sure everything is up to date.

I always use database type "MySQLi". The server is running MariaDB. Very strange behavior and even stranger that it just disappeared.

It's possible it was just a caching issue which would explain it clearing up suddenly.
