  def createPresentation(
      presentationRequest: PresentationRequest,
-      credentials: Seq[Credential],
+      credentialRequests: Seq[CredentialAndRequestedAttributesPredicates],


would it be a good naming:
presentationRequest: AnonCredsPresentationRequest?

@CryptoKnightIOG, can you create a test for this issue and a ticket in the jira or add any other documentation that describes this issue?

This was added by Fabio. Will follow up with him.

in my personal opinion a good name for CredentialAndRequestedAttributesPredicates is CredentialRequests or AnonCredsV1.CredentialRequests (if we can isolate the types the corresponds to the V1)

+      maybeRecord <- presentationRepository
+        .getPresentationRecord(recordId)
+        .mapError(RepositoryError.apply)


I think, it's a good practice to call logError as well before mapError, so we can track what exactly is wrong

The best way to handle this should defined in the ADR part of the Error Management value brief. I'll add this specific case - call to mapError() - to the list 👍

I would recommend extracting this logic into the method. Something like resolveSchema(schemaId)

  }


the method is tooooo long :)
try to refactor it to a sequence of smaller functions next time.

Probably, a good idea for refactoring is to create a package or object AnoncredsV1 and all corresponding domain classes. RequestedAttribute etc.

Yep good idea

Good job, @CryptoKnightIOG! Keep codding 👍

Similar to what we did for the IssueBackgroundJobs class, I propose to move the logic for each case to the PresentationService implementation. It initially leaked to the background job class because Pollux had no access to the ManagedDIDService, which is now solved.

Note that it implies a bit of refactoring (also at the unit tests level!), so we could handle this as a tech-debt item if we don't want to hamper the delivery of this verification Epic 👍

Yes, I will do a refactor. In the end, because there are patterns forming.

Do you need any help with those errors (e.g. from Fabio)?

@bvoiturier these were added by Fabio. Could be great if someone can have a look at them.
