Things to validate:
Can you reference an existing key in the same method block?
E.g.,
[ { "id": "did:web:00d9-83-248-113-71.ngrok.io:api:4dbac1c5-2430-459d-8ef6-e3f2327221ff#8JL0i2r1SFDKnhr2pGdEx5FAzkCHs30EAjA5s9M8JPo", "type": "JsonWebKey2020", "controller": "did:web:00d9-83-248-113-71.ngrok.io:api:4dbac1c5-2430-459d-8ef6-e3f2327221ff", "publicKeyJwk": { "crv": "P-256", "kty": "EC", "x": "NhB5TYSxqR_x_0vMpmfdpN3KI6C11tzE6r_xDqbVy9Q", "y": "nhuaiyE61qQ6A2Sh8loFjh49asQeFqaKD0zKzjESu8s" } }, { "id": "did:web:00d9-83-248-113-71.ngrok.io:api:4dbac1c5-2430-459d-8ef6-e3f2327221ff#8JL0i2r1SFDKnhr2pGdEx5FAzkCHs30EAjA5s9M8JPo" } ]
