Fixed a "superfluous response.WriteHeader" warning occurring in the RunSSEHandler. The handler was explicitly setting a 200 OK status before entering the event stream loop, which caused conflicts if an error occurred early and the error middleware attempted to write a 500 status.

Summary of Changes

Hello @indurireddy-TF, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a warning related to 'superfluous response.WriteHeader' in the RunSSEHandler. By removing the premature setting of a 200 OK status, the change ensures that error handling middleware can correctly set appropriate HTTP status codes when errors occur early in the Server-Sent Events (SSE) stream, improving the robustness of error reporting.

Highlights

  • Fix superfluous WriteHeader warning: Removed the explicit http.StatusOK write in RunSSEHandler to prevent conflicts with error handling middleware.

Code Review

This pull request addresses a "superfluous response.WriteHeader" warning in the RunSSEHandler. The change removes the explicit call to rw.WriteHeader(http.StatusOK) before the event stream loop. This is the correct approach, as it allows Go's net/http server to implicitly write the 200 OK status on the first successful write to the response body. More importantly, if an error occurs before any data is written, this change allows the error-handling middleware to correctly set a different status code (e.g., 500). The fix is correct and effectively resolves the bug.
