Proof Predicate issue #216

There are a few issues that I have ran to while trying to use the proof predicate.

  1. Returning empty credentials. The function ListCredentialsForProofRequestAsync returns an empty list when request_predicates is included in the proof request JSON. I have worked around this by converting it into requesting_attribute to get the needed credentials id before converting it back to request_predicates later.

  2. Error: "A value being processed is not valid.". When creating the proof presentation. From what I know the value should be in the correct format, both are int which now I'm not sure why it is happening. Did anyone manage to successfully create a proof predicate with hyperledger dotnet?

For reference: this is the JSON used to request predicate

@"{
""name"":""Proof Request"",
""version"":""1.0"",
""nonce"":""1234567890"",
""requested_predicates"":{
""dob"" : {
""name"": ""age"",
""p_type"": ""<="",
""p_value"": 18,
}
},
""non_revoked"":{
""to"": 2147483647
}
}";

Thank you in advanced!
