Research direction
Examine the existing e2e tests in the repository (e.g., in the 'examples' or 'internal' directories) to understand the testing framework. Study how the gRPC gateway handles HTTP headers and converts them to gRPC metadata. Then implement a test that sends a request with a specific header and verifies that it is propagated to the gRPC service's context. No linked PRs or comments are available for this issue.
