the issue here is the documentLoader could not dereference the url for your did json-ld context: https://www.w3.org/ns/did/v1. You can pass in a documentLoader as a parameter to sign. The other problem might be that your existing documentLoader needs to know where to load that context from. This might be a little confusing, but just because a context has a url does not necessarily mean it will be fetched from the internet. Some of the more secure implementations of jsonld only fetch json-ld contexts from local sources as a security precaution.
