/present-proof-2.0/send-proposal throws exception on the verifying side

[etschelp]

I'm trying to send a indy proof proposal via /present-proof-2.0/send-proposal, as I learned this endpoint now expects a proof request vs the v1 proposal. So to replicate the v1 behavior I'm sending a very specific proof request that describes my intended proposal as close as possible. So this is my payload:

{
    "by_format": {
        "pres_proposal": {
            "indy": {
                "name": "Test V2",
                "version": "2.0",
                "requested_attributes": {
                    "iban": {
                        "name": "iban",
                        "restrictions": [
                            {
                                "schema_id": "M6Mbe3qx7vB4wpZF4sBRjt:2:bank_account:1.0",
                                "cred_def_id": "EraYCDJUPsChbkw7S1vV96:3:CL:571:bob-bank-04",
                                "attr::iban::value": "mytestvalue"
                            }
                        ]
                    }
                },
                "requested_predicates": {}
            }
        }
    }
}

This works on the proofing side, but the verifier logs the following exception:

2021-11-01 14:42:08,959 aries_cloudagent.core.conductor ERROR Exception in message handler:

    indy_proof_request["name"] = request_data.get("name") or "proof-request"
AttributeError: 'NoneType' object has no attribute 'get'

By looking at the handler this kind of makes sense, because the variable that handles the request is assigned as a None type as a default which probably means it is not assigned as intended.

  async def create_bound_request(
        self,
        pres_ex_record: V20PresExRecord,
        request_data: dict = None,
    )
        // ...
        indy_proof_request["name"] = request_data.get("name") or "proof-request"

Also ran into this, @shaangill025 are you currently working on a solution for this?
