Example code is broken

[aljones15]

The README contains this snippet:

import vc from '@digitalbazaar/vc';

// Required to set up a suite instance with private key
import {Ed25519VerificationKey2020} from
  '@digitalbazaar/ed25519-verification-key-2020';
import {Ed25519Signature2020} from '@digitalbazaar/ed25519-signature-2020';

const keyPair = await Ed25519VerificationKey2020.generate();

const suite = new Ed25519Signature2020({key: keyPair});

The above code is fine but trying this:

const verifiableCredential = await vc.issue({credential, suite});
/* throws:
        TypeError: "suite.verificationMethod" property is required.
    at Proxy.issue (node_modules/@digitalbazaar/vc/lib/vc.js:120:11)

{
  suite: Ed25519Signature2020 {

  }
}

Basically the verificationMethod is missing when creating an Ed25519-verification-key-2020 I believe we need a did key here.

Also see #93. The 2020 tests haven't been added yet. The tests and README examples need updating.

Can we get an update on this. It's been a month.

[dmitrizagidulin]

This issue has been addressed in recent vc-js versions. (Specifically, verificationMethod is now being determined in
jsonld-signatures _processSignatureParams() from the suite/key, when appropriate.)

Why has this issue been closed? The problem is still not resolved. Today, over 3 years later, I still have the exact same problem when I run the example code from the website.

[dlongley]

Rather than reopening this since the examples have changed significantly, I've opened a new issue for someone to ensure the examples are runnable and refresh them as needed: #185.
