Current Behavior

Validation checking prevents empty credentialSubject

Expected Behavior

JWSTestSuite is expecting empty credentialSubject to succeed. It’s used as credential-0.json in the input test vectors.

{
  "@context": [
    "https://www.w3.org/2018/credentials/v1",
    "https://w3id.org/security/suites/jws-2020/v1"
  ],
  "type": ["VerifiableCredential"],
  "issuer": "did:example:123",
  "issuanceDate": "2021-01-01T19:23:24Z",
  "credentialSubject": {}
}

Note that this is the reason test vector credential-0 is failing.

Failure Information

Receive error:

TypeError: credentialSubject must not be empty

Steps to Reproduce

Clone JWS-Test-Suite and then:

cd  JWS-Test-Suite/implementations/did-jwt-vc
npm run install
npm run test

It seems that the behavior is correct (see #107) so I’m closing this

@mirceanis, no need to create a CODEOWNERS file – I just want to help handle PRs, issues, etc. Ack on semantic versioning. I’ll make sure I’m subscribed to did-jwt as well
