jsonld-signatures-bbs: TypeError: suite.ensureSuiteContext is not a function

This is caused by recent changes in https://github.com/digitalbazaar/jsonld-signatures

Here is an example implementation that would remove this error:

import sec from '@transmute/security-context';

ensureSuiteContext({ document }: any) {
    const contextUrl = sec.constants.BLS12381_2020_V1_URL;
    if (
      document['@context'] === contextUrl ||
      (Array.isArray(document['@context']) &&
        document['@context'].includes(contextUrl))
    ) {
      // document already includes the required context
      return;
    }
    throw new TypeError(
      `The document to be signed must contain this suite's @context, ` +
        `"${contextUrl}".`
    );
  }

^ this implementation supports it… feel free to help port it here.

The function is required by digital bazaar, the context url is in the form we agreed to use during the did WG.

Hi @OR13 https://github.com/OR13 thanks for the link! I’m trying to understand the differences between these two implementations. Is there a specific reason the Transmute implementation requires the https://w3id.org/security/suites/bls12381-2020/v1 context on the input doc and this MATTR one doesn’t?

Mainly asking because I don’t see any mention of this context in the BBS spec either.
