The funny thing is, this error message is hardly less useful than the recent trend of error messages which say only, "Something went wrong".

What would you expect? IME these are mostly unforeseen 500 errors, logged internally, and not something a client can do anything about (or should know anything about, for security reasons).
Have you never dealt with customers reporting errors?
Something went wrong is what they will tell you and expect an answer. Doesn’t matter how fancy and detailed the error, you will get back, “it’s broken fix it.”
