Internal Server Error when accepting group join

Hello,

On a discourse instance we use groups where owners have to validate people.
Recently, we started seeing errors when owners try to accept people into groups. I’m not sure if it applies to particular groups, owners or users.
A pop up “Internal Server Error” is shown, and the frontend still believes the request was successful (the UI shows the user as “accepted”). However when reloading we can see that it’s not the case and the request is still pending.

This error leaves 2 log messages:

A fatal

I’ve seen a couple of these recently. It’s because the particular user that’s being accepted to the group has a blank locale for some reason (rather than null or a specific value like en).

A fix has been put in place to prevent this error:

If you update your site and pull that fix in that should stop those errors and allow those users to be accepted to the group. :+1:

Indeed, that fixed it. Thanks !
