The biggest issue I have with most error messages is that they say things like you have here but don't reflect back the data that caused the error, i.e. show me the phone number you think I sent you.
I think this context is really hard to carry around, and if you aren’t extra super careful you can end up leaking passwords and other secret bits of memory here to logs. Better to just give me a place to put a debugger breakpoint IMO.
