What happened?
When a server raises an exception, such as when supplying a context ID that is > 36 chars, the client receives a JSON RPC error object which includes the full internal error message that the server produced.
This is not good security practice to leak internal error messages like this, and could expose sensitive information.
A suggestion would be to redact any internal error messages, and perhaps create a mapping of common errors to client friendly error messages.
If the intention is for implementations to handle this themselves, with patching or intercepting, which is likely what we will be doing, it should be at least documented.
