I’m unfamiliar with this error, but I’ll look into it. Are you still experiencing the same problem?

What I get from googling the “Malformed \uxxxx encoding” I would guess that you have somewhere, in the app name or a formula or data resource or logic, a lone \ which causes this problem. If you need to use \ somewhere in a formula etc., use \\ and it will appear as \.

ah so you had already posted about this here :sweat_smile: We’re looking into handling this in the future better.
