Error while using verification endpoint from wallet API

[eminademburan]

I am running the wallet, issuer and verifier API standalone as stated in this link https://docs.oss.walt.id/wallet/api/setup/open-source. While using the verification endpoint from the wallet API, I get an error. I am using the following endpoint.

/wallet-api/wallet/{wallet}/exchange/usePresentationRequest

You can see the error in the attached file. I do not get the error when I run the APIs using docker compose, but I get the error when I run the containers in standalone. Can you help with that?

judging by the logs, exchange/usePresentationRequest is provided an unresolved value for the presentationRequest field (the presentation_definition parameter is missing from the url).

Generally speaking, a presentation requires 3 steps (unlike the single step for credential claiming):

1. resolve presentation request

/wallet-api/wallet/{wallet}/exchange/resolvePresentationRequest

• the response is a complete presentation request, URL-encoded
• this url contains the resolved presentation_definition

2. match presentation-definition credentials
   • by providing the presentation_definition from step#1

/wallet-api/wallet/{wallet}/exchange/matchCredentialsForPresentationDefinition

• the response is a list of credentials matching the presentation definition
• however, this step can be skipped if the credential-id's are already known

3. create the presentation
   • by providing the did
   • and the resolved presentation-request-url (which should include the presentation_definition parameter)
   • and the list of credential-id's
   • optionally, the disclosed properties and a note can also be provided

/wallet-api/wallet/{wallet}/exchange/usePresentationRequest

You can also resolve the presentation-definition manually by fetching it from the presentation_definition_uri that can be found in the original presentation-request-url, attach it as a value for the presentation_definition parameter and supply this updated presentation-request-url to the exchange/usePresentationRequest api. However, this might not work for all requests.

walt.id documentation provides more details on how to present a verifiable credential using oid4vc.

Thank you for your help @mikeplotean. I skipped the first step and I think it was the reason why I got this error. The issue was resolved.

Good job! @mikeplotean
