Error creating contracts

[johnnychoque]

Hi all,
Using "transfer samples" I have successfully created two assets with Id "assetId-1" and "assetId-2", and also two policies with Id "Policy-A" and "Policy-B", but when I try to create a contract for a specific asset and policy, the API returns an error message. Maybe I have not specified correctly the value of the "assetsSelector" parameter, is there any documentation that can help me?

Request:

curl --location 'http://localhost:19193/management/v2/contractdefinitions' \
--header 'Content-Type: application/json' \
--data-raw '{
  "@context": {
    "@vocab": "https://w3id.org/edc/v0.0.1/ns/"
  },
  "@id": "1",
  "accessPolicyId": "Policy-A",
  "contractPolicyId": "Policy-A",
  "assetsSelector": ["assetId-1"]
}'

Response:

the assetsSelector (as stated in the API docs) is of type Criterion, not string.
you can find the schema for the Criterion type also in the API docs
