DSP: odrl:action / odrl:type / action is null

[matgnt]

From examples I can see EDC uses policy permissions with this:

                "odrl:action": {
                    "odrl:type": "USE"
                },

In the DSP specs I could not find examples like that.
There I found examples like:

 "odrl:action": {
            "@id": "odrl:use"
          },

or simply

"action": "use"

I used the latter one to interact with EDC /negotiations/{process_id}/agreement and receive EDC error messages like:

java.lang.NullPointerException: Cannot invoke "org.eclipse.edc.policy.model.Action.getType()" because "action" is null                                                     
edc-dev-env-consumer-control-plane-1  |         at org.eclipse.edc.jsonld.transformer.from.JsonObjectFromPolicyTransformer$Visitor.visitAction(JsonObjectFromPolicyTransformer.java:225)

It seems to me, EDC would expect this in a different format that I can find in DSP examples. I hope this is not some fancy Jsonld formatting issue again ;-)

I tried to find any information about this odrl:action / odrl:type thing, but no luck.

Any thoughts?

Closing this issue, because it seems to work as expected also without the type. Not sure what caused this error reported above.
