Please add better error message for when a DID tries to issue a credential to itself #878
Description
Expected behaviour
I would have been able to debug my problem much faster if the error message was
{
"message": "The DID in the request cannot be the same as the credentialSubject. In other words, you cannot issue a credential to yourself."
}
The problem is that you cannot have the DID in the request URL be the same as the DID in the credentialSubject.
IOW, you cannot issue a credential to yourself. I guess that makes sense, but the message could be clearer. I will issue a feature request for that.
Actual behaviour
Instead, I was stuck for a long time trying to understand what
{
"message": "cannot parse claim"
}
meant. Even after reading this, I was not sure. It took some experimenting in postman before I realized what was going on.
Steps to reproduce the problem
Try to issue a credential to the issuer.
