Bitwarden "cannot read properties of undefined" (reading to tolowercase)

Thanks for confirming that. I would recommend updating to the latest server version to see if this resolves the issue.

And, I’ll point to my post above highlighting the risks of allowing automatic client updates if you are not keeping your server on a recent version.

With that said, you probably should review the recent reminder about Bitwarden’s support window when it comes to client/server compatibility. If you are not keeping your self-hosted server within a couple versions of current, it can be risky to allow the apps to be on the most recent version.
