I agree that it’s (weirdly) uncommon to be the one saying “please give me more info about the error!”

A simple error code can be endlessly helpful (bonus points if there’s a corresponding support article explaining common codes)

Even if some codes are only useful to internal support, it’s handy to be able to search an error code and see “oh I can just jump straight to submitting a ticket/calling their support” or “oh, this fix might work”
