IOS bundle: unhandled JS exception: Invalid regular expression: invalid group specifier name

My bundle builds successfully but when it is opened in expo go it fails with the error Unhandled JS Exception: Invalid regular expression: invalid group specifier name no stack. There is no backtrace to look through and the extra info tab doesn’t show anything. I don’t think it gets to any of my application code before the exception. Anyone know how to debug this?

Alright, appears to be an error in the cbor npm package. It runs fine in the browser but IOS doesn’t like it apparently.

Hey, I’m getting this error here on iOS and macOS Safari: SyntaxError: Invalid regular expression: invalid group specifier name It comes from here: // Remove.
