0.17.0: "5.6 Get EndpointDataReference" failed

[markuskugelmann96-ux]

After obtaining the "TRANSFER_PROCESS_ID" the Step "5.6 Get EndpointDataReference" "ControlPlane Management/Get Cached EDRs" produces a "HTTP ERROR 404 Not Found" that indicates that "edr-cache-api"-Extension is missing.

✅ Bug fixed

I was able to reproduce this on release/0.17.0 and found the root cause.

Problem

The Bruno collection was using the wrong API version for the EDR endpoints.

It currently calls the v4 EDR management endpoint:

/api/mgmt/v4/edrs/{id}/dataaddress

but the backend exposes the EDR DataAddress endpoint on v3:

/api/mgmt/v3/edrs/{id}/dataaddress

Root cause

Commit a97bdcb (fix: upgrade to MgmtAPI v4) updated the Bruno requests from v4beta to v4 for the management API flow, but the EDR endpoint still needs to use v3.

The error suggesting that the edr-cache-api extension is missing was misleading in this case. The EDR metadata was present in the consumer controlplane database; the request was just sent to the wrong API route.

Verification

This returned 404 Not Found:

GET /api/mgmt/v4/edrs/{id}/dataaddress

This returned 200 OK:

GET /api/mgmt/v3/edrs/{id}/dataaddress

Verified locally with Podman + KinD:

curl -i -X GET "http://127.0.0.1/api/mgmt/v3/edrs/<transferProcessId>/dataaddress" \
  -H "Host: cp.consumer.localhost" \
  -H "X-Api-Key: password"

Fix

I corrected the following files in my fork:

• Requests/ControlPlane Management/Get cached EDRs.bru
• Requests/ControlPlane Management/Get EDR DataAddress for TransferId.bru
• README.md

The working version is available in my fork/PR:

[paullatzelsperger]

this should be (temporarily) fixed with this commit. Be aware that the entire dataplane/EDR is undergoing major refactoring, so expect changes there.

[paullatzelsperger]

the EndpointDataReference feature will be removed once a proper Dataplane Signaling dataplane is implemented.
