VP proofs being created with "undefined" verificationMethod #147
Description
In the Readme example for signing a VP, it is not clear where the verificationMethod - "https://example.edu/issuers/keys/1" comes from.
When I attempt to recreate the example locally using my own did:key for signing, I get an undefined verificationMethod.
Any ideas where I am going wrong here? Is verificationMethod something that should be passed in somehow.
