Verify Invocation Assumes Delegation

[wip-abramson]

Using the node module, I am attempting to verify the invocation of a root capability. I.e. a capability before it has been delegated.

I run into the error: missing field parentCapability``

I believe this is because the verify_invocation funtion is expecting a Delegation.

I could also just be implementing this wrong. But have you tested verifying an invocation of a root capability?

I seem to be able to generate the root invocation without issues.

{
  '@context': 'https://w3id.org/security/v2',
  id: 'urn:uuid:ad86cb2c-e9db-434a-beae-71b82120a8a4',

    capability: 'urn:zcap:root:did%3Akey%3Az6MkrtW3VfiCytTetfGhpj1aERSBqwUT2zsvwu6djfDkgZcN'
  }
}

I just can't verify.

I have managed to verify an invoked delegation of this capability however.
