Its hard to understand what is wrong with this error

Im trying to make a ION did with this setup, but get a strange error which does not lead me to anything. See after code

    const key = await Bls12381G2KeyPair.generate();
    const jwk = key.toJsonWebKeyPair();
    const did = new ION.DID({
      content: {
        publicKeys: [
          {
            id: 'primary-issuing',
            type: key.type,
            publicKeyJwk: jwk.publicKeyJwk,
            purposes: [ 'assertionMethod' ]
          }
        ],
        services: [
          {
            id: 'did-comm-agent',
            type: 'DIDCommMessaging',
            serviceEndpoint: 'https://mymagicaldidcomurl/messaging',
            accept:[
              "didcomm/v2",
              "didcomm/aip2;env=rfc587"
            ],
          }
        ]
      }
    });

Unexpected 5xx response: {"requestId":"1cbecd445bc68f48a1d34a257946d24c","date":"Wed, 22 Sep 2021 14:37:29 GMT","message":"continuation_storage_uncaught_exception: Error: document_composer_service_has_missing_or_unknown_property"}

Im not finding any place this is referenced in the SDK or the tool itself. How can I debug this? I thought it was all up to speed.

Things work with this one, so just keen on understanding

let authnKeys = await ION.generateKeyPair();
let did = new ION.DID({
  content: {
    publicKeys: [
      {
        id: 'key-1',
        type: 'EcdsaSecp256k1VerificationKey2019',
        publicKeyJwk: authnKeys.publicJwk,
        purposes: [ 'authentication' ]
      }
    ],
    services: [
      {
        id: 'domain-1',
        type: 'LinkedDomains',
        serviceEndpoint: 'https://foo.example.com'
      }
    ]
  }
});

I think the reason we needed to switch to JsonWebKey2020 was because contexts for other types were missing the publicKeyJwk property and so the public key was being dropped from the did document when it was being loaded by a document loader to verify credentials with vc.js. I believe this was specific to the digital bazaar libraries we were using though and you may not encounter them if you use a different library or a different credential format.

From did core

Each service extension MAY include additional properties and MAY further restrict the properties associated with the extension.

That’s a heck of a lot of optionality 😃
