VCNetworking.DecodingError

[mclasson]

When I try to validate a given credential (successfully stored in wallet) I can see in the backend that Authenticator calls presentation-request.jwt and gets the token. But then it says as below "DecodingError - unableToDecodeToken".

Where can I begin to troubleshoot this?

ERRO VerifiableCredential 0 TID=1 79 (fetchFromUrl(url:)) Error: Error: VCNetworking.DecodingError code: 0 Message: Failed to get the presentation request Properties: ["Line": "79", "Message": "Failed to get the presentation request", "Function": "fetchFromUrl(url:)", "CorrelationVector": "jvgvxzaoTiygyTOkIv/Sdw.0", "File": "/Users/runner/work/1/s/PhoneFactor/VerifiableCredentialWallet/VerifiableCredentialWallet/ViewModel/RequestProcessorViewModel.swift", "Error": "Error: VCNetworking.DecodingError code: 0"]

I am getting the same error in the Authenticator App (iOS). I cannot not add the VC to my wallet.

@backbone2k My error here was that I made credentialType an array twice. once in const credentialType = ['sdfsdf'];

and then again in

input_descriptors: [
        {
          id: "expert",
          schema: {
            uri: [credentialType],
          },

Hi @mclasson,

I have not changed the input_descriptors array. Only modified the credntialType const. I am not sure about the documentation when it comes to the Azure KeyVault. Have you made any changes to the didconfig.json at all ot the the variables: kvVaultUri, kvSigningId and kvRemoteSigningKeyId? The documentation explains to note down certain information from the newly created KeyVault but these are not used in the following parts....

I am really not getting what I did wrong :-(

[mclasson]

@backbone2k Yes, they are all my values. You get them from this page https://portal.azure.com/#blade/Microsoft_AAD_DecentralizedIdentity/InitialMenuBlade/issuerSettingsBlade copy the did and paste it here https://identity.foundation/ion/explorer/ to get the kvSigningKeyId. The azClientId and azClientSecret you got from where you did the AppRegistration

[backbone2k]

@mclasson Ah ok - but the azClientId and Secret are the second Tutorial / Part. I got stucked yesterday in the first example where you still use the MS B2C demo environment (https://docs.microsoft.com/en-us/azure/active-directory/verifiable-credentials/enable-your-tenant-verifiable-credentials) - But maybe I just toss this one and head over to the second part :-)

Hi @johncra,

thank you very much for your awesome resources on DID/VC. I started over from scratch, cloned the repo and made the modifications to the issuer app.js file - same issue. I think your information on "waiting" for the VC instance was the point I was missing. I think I was unpatient... Now it is working ;)

I am glad it’s working!
