Could not create a Policy

[Akshay-a-j]

Hello,

I attempted to replicate the transfer-06-consumer-pull-http scenario but encountered difficulties in creating a policy.

I had previously succeeded in doing so a few days ago. However, after cloning the Samples repository again and attempting to replicate the process, I encountered an error when trying to create the policy using the provided set of commands.

curl -d '{
"@context": {
"edc": "https://w3id.org/edc/v0.0.1/ns/",
"odrl": "http://www.w3.org/ns/odrl/2/"
},
"@id": "cPolicy",
"policy": {
"@type": "set",
"odrl:permission": [
{
"odrl:action": "USE",
"odrl:constraint": [
{
"odrl:leftOperand": "ids:absoluteSpatialPosition",
"odrl:operator": "EQ",
"odrl:rightOperand": "eu"
}]
}
],
"odrl:prohibition": [],
"odrl:obligation": []
}
}' -H 'content-type: application/json' http://localhost:19193/management/v2/policydefinitions
-s | jq

and the error message was:

[
{
"message": "http://www.w3.org/ns/odrl/2/Operator property '@id' was missing",
"type": "InvalidRequest",
"path": null,
"invalidValue": null
},
{
"message": "ARRAY must be EQ, NEQ, GT, GEQ, LT, LEQ, IN, HAS_PART, IS_A, IS_ALL_OF, IS_ANY_OF, or IS_NONE_OF but was: unknown",
"type": "InvalidRequest",
"path": null,
"invalidValue": null
}
]

Could someone kindly inform me of the potential cause of this issue?

Thank you

Update: We can create policy if "permission":[ ] is empty. However, it fails to create a policy when above given permission is included in the command.

please try to add the odrl.jsonld file as context:

{
  "@context": {
    "edc": "https://w3id.org/edc/v0.0.1/ns/",
    "odrl": "http://www.w3.org/ns/odrl/2/"
  },
  "@id": "cPolicy",
  "policy": {
    "@context": "http://www.w3.org/ns/odrl.jsonld",
    "@type": "set",
    "permission": [
      {
        "action": "USE",
        "constraint": [
          {
            "leftOperand": "ids:absoluteSpatialPosition",
            "operator": "EQ",
            "rightOperand": "eu"
          }]
      }
    ],
    "prohibition": [],
    "obligation": []
  }
}

(PS: please use triple backtick block to monospaced code, otherwise it will become unreadable ;) )
