Request data from a Provider Backend through a Consumer DSC failed

[gonzalogil26]

Hi,

I have the following DSCs running:

• Data Provider: https://ids-dataprovider.tekniker.es:8080
• Data Consumer: https://ids-dataconsumer.tekniker.es:8080

I have configured an artifact (REST API Provider Backend) on the Data Provider and I have already agreed a contract for it between the Data Consumer DSC and Data Provider DSC. The contract agreements URIs for the data provider and data consumer can be seen as follows:

• Data Provider DSC --> remoteId: https://ids-dataprovider.tekniker.es:8080/api/agreements/f28bf299-2a8a-47c7-96ca-88036ceedfbc
• Data Consumer DSC --> https://ids-dataconsumer.tekniker.es:8080/api/agreements/45f53be9-aeba-47ee-bbb8-1781b54a8028

Furthermore, at the Data Consumer DSC I have already get the Id of the artifact agreed based on the following HTTP GET: https://ids-dataconsumer.tekniker.es:8080/api/agreements/45f53be9-aeba-47ee-bbb8-1781b54a8028/artifacts

• artifact Id: https://ids-dataconsumer.tekniker.es:8080/api/artifacts/a30d8109-29c9-4ada-be59-dbeebe6ddacb

However, when I tried to retrieve the data from the Provider Backend through the Consumer DSC (GET https://ids-dataconsumer.tekniker.es:8080/api/artifacts/a30d8109-29c9-4ada-be59-dbeebe6ddacb/data), something goes wrong in the communication between the Connectors.

Request to the Data Provider Backend through the Data Consumer DSC:

Logs at the Data Provider DSC:

My concer is wether I am really doing the correct request to retrieve the data from the Provider backend through the DSC consumer. Could someone help me?

Thanks.
