Policy in the contract agreement is not equal to the one in the contract offer

[masud-svg]

Hello,

I have been exploring EDC for the past couple of days. I am facing an issue which is like I have set up a policy as a provider

  "@context": { 
        "@vocab": "https://w3id.org/edc/v0.0.1/ns/" 
   },
  "@id": "bPolicy",
  "policy": {
    "@context": "http://www.w3.org/ns/odrl.jsonld",
    "@type": "Offer",
    "odrl:permission": [{
        "odrl:action" : "USE",
        "odrl:target": "IESE-1300",
        "odrl:constraint": [{
            "leftOperand": "dateTime",
            "operator": "lt",
            "rightOperand": { "@value": "2024-06-01", "@type": "xsd:date" }
        }]
    }],
    "prohibition": [],
    "obligation": []
  }
}

And now as a client when I am trying to contarct negotiation, but it shows Policy in the contract agreement is not equal to the one in the contract offer

My posted data for contarct negotiation is

  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/",
    "odrl": "http://www.w3.org/ns/odrl/2/"
  },

    "offerId": "MQ==:SUVTRS0xMzAw:MTU1YTlmYWEtNDg1MS00ZDU3LWEyZTQtOWJkOWIzMzE1ZGQ1",
    "assetId": "IESE-1300",
    "policy": {
      "@type": "odrl:Offer",
      "odrl:action": "USE",
      "odrl:permission": [{
        "odrl:target": "IESE-1300",
        "odrl:action": {
          "odrl:type": "USE"
        },
        "odrl:constraint": [{
          "leftOperand": "dateTime",
          "operator": "lt",
          "rightOperand": { "@value": "2024-06-01", "@type": "xsd:date" }
        }]
      }],
      "prohibition": [],
      "obligation": [],
      "odrl:target": "IESE-1300"
    }
  }
}

Could anyone tell me what went wrong here?

Hi @masud-svg can you also paste what's returning from the catalog request for the "assetId": "IESE-1300"?

Thanks

Hello,

I also get the same error message as @masud-svg. how can I get the policy already included in the contract agreement and in the contract offer after having started the negotiation process? I have tried to use the Management API (https://app.swaggerhub.com/apis/eclipse-edc-bot/management-api/0.6.1) but I have not found the API that performs those functionalities.

Thanks in advance.

@masud-svg Before we can investigate this, we need a bit more information.

1. How did you make the catalog request, i.e. did you use two EDCs, one sending the request to the other, or did you use Postman/curl/... directly?
2. in either case: can you provide the requests you were sending (please link a gist, do not post as inline text)
3. what's the exact version of EDC you're on?
4. do you have a reproducible test case which we can investigate, preferably in a gist?
5. are you referring to "literal equality", i.e. "does not match character by character", or are you referring to "semantic equality", i.e. "one has different information than the other"?

[ndr-brt]

Which version of EDC are you using?
Please note that target should not be used anyway because in the DSP protocol it's used to identify the asset involved in the negotiation

[johnnychoque]

@paullatzelsperger This is the gist of my case https://gist.github.com/johnnychoque/026ca3bfcf223da2f62929c063adf0d4.
I am using the current version of Samples Transfer. According to lib.versions.toml file I am using edc 0.6.0.
