Headers are not sent to Datasource endpoint

• HTTP Data Transfer: Headers not included in transfer request edc-ui#702
• Content-Type header ignored edc-ui#660
  • Transfer: Pass the Content-Type header with its specific URI edc-ui#661

Description

When creating an asset it is possible to add additional headers to be passed to the Datasource endpoint.
For this purpose, in the create asset request, we added an x-api-key header and set its value to peanutbutter so that the https://w3id.org/edc/v0.0.1/ns/dataAddress field looks like this:

"https://w3id.org/edc/v0.0.1/ns/dataAddress": {
    "https://w3id.org/edc/v0.0.1/ns/type": "HttpData",
    "https://w3id.org/edc/v0.0.1/ns/baseUrl": "{{PROVIDER_EDC_SOURCE_URL}}",
    "https://w3id.org/edc/v0.0.1/ns/method": "GET",
    "https://w3id.org/edc/v0.0.1/ns/header:x-api-key": "peanutbutter"
}

Using this created asset, and following the rest of the steps in the postman collection, we managed to start the data push.
Our Datasource endpoint was hit correctly, however, the x-api-key header was not received.

Expected Behavior

Upon transfer, we expect the additional headers to arrive to the Datasource endpoint.

Observed Behavior

Upon transfer, no additional headers arrived to the Datasource endpoint.

Steps to Reproduce

Steps to reproduce the behavior:

1. Import the postman collection in Postman
2. In Variables, set PROVIDER_EDC_SOURCE_URL to a simple server that prints the headers of all requests it receives. We used this gist.
3. Go to request 1 Create Asset, then Body and add the following inside the https://w3id.org/edc/v0.0.1/ns/dataAddress field:

"https://w3id.org/edc/v0.0.1/ns/method": "GET",
"https://w3id.org/edc/v0.0.1/ns/header:x-api-key": "peanutbutter"

4. Send the rest of the requests in order: 2 Create Simple Policy, 3 Create ContractDefinition, 5 Start Negotiation, 6 Request Contract Agreements
5. Get the contract agreement @id from the response of 6 Request Contract Agreements and paste it in the Body of 7 Start Data Push replacing the value of https://w3id.org/edc/v0.0.1/ns/contractId.
6. Send the 7 Start Data Push request
7. Check your Datasource server logs, where the x-api-key header is missing from the received request.

Should work by now, if not please let us know again. However, the properties should be as follows in the dataAddress:

authKey -> optional authentication header, e.g. "X-Api-Key"
authCode -> optional authentication value, such as the actual API-key
