request URL : https://dids.testnet.verida.io:5001/load?did=did:vda:0x68fCc963f0B6057Bd48b2714F14B3305B81621b1

I get this error :

Steps to reproduce

      import { Resolver } from 'did-resolver';
      import vdaResolver from '@verida/did-resolver';
      
      const DID_REGISTRY_ENDPOINT = 'https://dids.testnet.verida.io:5001';

     	async verifyCredential(vcJwt: string): Promise<void> {
		const resolver = this.getResolver();
		return verifyCredential(vcJwt, resolver);
	}

	getResolver(): any {
		const resolver = vdaResolver.getResolver(DID_REGISTRY_ENDPOINT);
		return new Resolver(resolver);
	}
