created accress and contract policies but i cannot get the contract agreement id

[ghost]

Hi,
I created an access and contract policy in the transfer-sample. However, I have some issues to obtain the contract agreement id. The contract negotiation terminates and I don't really know why? Here is my access policy:

{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/",
    "odrl": "http://www.w3.org/ns/odrl/2/"
  },
  "@id": "eu-policy",
  "policy": {
    "@context": "http://www.w3.org/ns/odrl.jsonld",
    "@type": "Set",
    "permission": [
      {
        "action": "use",
        "constraint": {
          "@type": "AtomicConstraint",
          "leftOperand": "location",
          "operator": {
            "@id": "odrl:eq"
          },
          "rightOperand": "eu"
        }
      }
    ],
    "prohibition": [],
    "obligation": []
  }
}

and my contract policy:

{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/",
    "odrl": "http://www.w3.org/ns/odrl/2/"
  },
  "@id": "time-limit-policy",
  "policy": {
    "@context": "http://www.w3.org/ns/odrl.jsonld",
    "@type": "odrl:Set",
    "profile": "http://www.w3.org/ns/odrl/2/core",
    "https://w3id.org/edc/v0.0.1/ns/policy": {

    },
    "permission": [
      {
        "target": "assetId",
        "action": "use",
        "constraint": [
          {
            "@type": "AtomicConstraint",
            "leftOperand": "elapsedTime",
            "operator": "lt",
            "rightOperand": { "@value": "PT1H", "@type": "xsd:duration" }
          }
        ]
      }
    ]
  }
}

and this is my negotiation contract:

{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/",
    "odrl": "http://www.w3.org/ns/odrl/2/"
  },
  "@type": "ContractRequest",
  "counterPartyAddress": "http://localhost:19194/protocol",
  "protocol": "dataspace-protocol-http",
  "policy": {
    "@context": "http://www.w3.org/ns/odrl.jsonld",
    "@id": "MQ==:YXNzZXRJZA==:MzY0NDdkNWYtYTMyOS00NGY2LTgzNWMtOTUzYzBkNjQ1ZmMx",
    "@type": "Offer",
    "assigner": "provider",
    "target": "assetId",
    "permission": [
      {
        "@context": "http://www.w3.org/ns/odrl.jsonld",
        "@type": "odrl:Set",
        "profile": "http://www.w3.org/ns/odrl/2/core",
        "https://w3id.org/edc/v0.0.1/ns/policy": {

        },
        "permission": [
          {
            "and": [
              {
                "target": "assetId",
                "action": "use",
                "constraint": [
                  {
                    "@type": "AtomicConstraint",
                    "leftOperand": "elapsedTime",
                    "operator": "lt",
                    "rightOperand": { "@value": "PT1H", "@type": "xsd:duration" }
                  }
                ]
              },
              {
                "target": "assetId",
                "action": "use",
                "constraint": [
                  {
                    "@type": "AtomicConstraint",
                    "leftOperand": "location",
                    "operator": "eq",
                    "rightOperand": "eu"
                  }
                ]
              }
            ]
          }
        ]
      }
    ]
  }
}

Here are the logs:

Can anybody help me? Thanks
