Unable to share specific credential in a multi credential definition proof challenge.

[trta2352]

Wallet has 4 credentials. 2 times name_credential (same credential definition, different data) and 2 times email_credential(same credential definition, but different data). User then receives a proof challenge asking for both types of credentials. To fulfil the proof challenge user has to share 1 name_credential and 1 email_credential. But sine they have 2 of each type they have to choose which ones to share.

Using the following code I accept the proof challenge and I provide it with the filtered proof format containing the credentials I want to share.

   const acceptedRequest = await agent.proofs.acceptRequest({
            proofRecordId: proofRecord.id,
            proofFormats: credentialToShare,
          });

{
	"proofFormats":{
		"indy":{
			"attributes":{
				"f85c5f22-f03c-42cc-b597-1c8b1f292358":[
					{
						"credentialId":"51ce00f7-8351-47da-aa1c-2780f1d92bfb",
						"revealed":true,
						"credentialInfo":{
							"attributes":{
								"email":"[email protected]"
							},
							"credentialDefinitionId":"2jYo5xjBZe682KxZpxUyqY:3:CL:84:email_credential",

							"methodName":"indy"
						}
					}
				],
				"eed6a94d-e0d9-41a7-8390-34e1e55873d9":[

						}
					}
				]
			},
			"predicates":{

		}
	}
}

Agent in this case completely disregards what I added in the proofFormats parameter and defaults to the credentials it deems that fulfil the proof challenge.

Using this code:

  const _credentialsForRequest = await agent.proofs.getCredentialsForRequest({
        proofRecordId: proofExchangeRecord[0].id,
      });

I get this:

{
	"proofFormats":{

}

So even though Aries knows that multiple credentials fulfil the proof challenge it automatically reverts to the first credential that was added per credential definition. In this case for name_credential thats "Name 2" and for email_credential is "[email protected]".
