DotNet Edge Agent is unable to send a `Connectionless Presentation Message` to the DotNet Verifier Agent

[sahil-khanna]

Below is the scenario. EA = Edge Agent

• EA1 creates a Connectionless Proof Request
• EA2 scans the Connectionless Proof Request and creates a PresentationMessage as below

ProofRecord record = await proofService.ProcessRequestAsync(agentContext, Proof.RequestPresentationMessage, null);
(PresentationMessage presentationMessage, ProofRecord proofRecord) = await proofService.CreatePresentationAsync(agentContext, record.Id, requestedCredentials);

• The state of the ProofRecord on EA2 is Accepted
• EA2 sends the PresentationMessage as below

ServiceDecorator service = Proof.RequestPresentationMessage.GetDecorator<ServiceDecorator>(DecoratorNames.ServiceDecorator);
IMessageService messageService = App.Container.Resolve<IMessageService>();
await messageService.SendAsync(agentContext: agentContext, message: presentationMessage, recipientKey: service.RecipientKeys.First(), endpointUri: service.ServiceEndpoint, routingKeys: service.RoutingKeys?.ToArray());

In the above step, EA2 gets the error "Failed to send A2A message with an HTTP status code of InternalServerError and content".

Can anyone advise on the changes I need to make to get it working?

You are passing the wrong arguments for CreatePresentationAsync while creating a presentation for connectionless transport, You should use a different method.

• current arguments: CreatePresentationAsync(IAgentContext agentContext, string proofRecordId, RequestedCredentials requestedCredentials);

• actual arguments: CreatePresentationAsync(IAgentContext agentContext, RequestPresentationMessage requestPresentation, RequestedCredentials requestedCredentials);
