SSI DIM Wallet Stub can't create Industry Core Policy

[evegufy]

Current Behavior

When EDC contract offers are published with a policy like this, contract negotiation is terminated:

{
    "@context": {
        "odrl": "http://www.w3.org/ns/odrl/2/",
        "cx-policy": "https://w3id.org/catenax/policy/"
    },
    "@type": "PolicyDefinitionRequestDto",
    "@id": "traceability-core",
    "policy": {
        "@type": "odrl:Set",
        "odrl:permission": [
            {
                "odrl:action": "use",
                "odrl:constraint": {
                    "odrl:and": [
                        {
                            "odrl:leftOperand": "https://w3id.org/catenax/policy/FrameworkAgreement",
                            "odrl:operator": {
                                "@id": "odrl:eq"
                            },
                            "odrl:rightOperand": "traceability:1.0"
                        },
                        {
                            "odrl:leftOperand": "https://w3id.org/catenax/policy/UsagePurpose",
                            "odrl:operator": {
                                "@id": "odrl:eq"
                            },
                            "odrl:rightOperand": "cx.core.industrycore:1"
                        }
                    ]
                }
            }
        ]
    }
}

Expected Behavior

Contracts can be negotiated with any usage policy.

Steps To Reproduce

1. Publish EDC asset with the previously mentioned policy (Create EDC asset, policy and contract definition)
2. Start contract negotiation for the contract offer

@matbmoser @ds-jhartmann Once the description is ready. Please add Nitin, maybe also discuss in the Umbrella Matrix Chat.

Should not be a blocker for the community. Just use empty policies for now.

[matbmoser]

This is related with the policy, because the access policies will be checked against the wallet, and we usually configure the same policy for access and usage.

Why is the stub not accepting things by default???

@evegufy I added more details regarding policies.
@matbmoser please add additional information in case I forgot something or got something wrong

@ds-jhartmann the following error you sent via mail:

SEVERE 2024-11-25T09:42:01.416944841 JerseyExtension: Unexpected exception caught java.lang.NullPointerException: Cannot invoke "Object.toString()" because "v" is null at org.eclipse.edc.iam.identitytrust.service.IdentityAndTrustService.lambda$obtainClientCredentials$0(IdentityAndTrustService.java:114)

Is it related to this issue?

[ds-jhartmann]

@evegufy no, this is not related to the policies
