Thanks Andy, What you mentioned perfectly makes sense.
We will try to add handleHTTPResponse along with handleHTTPRequest to establish the fact. I attached the logs in logs.zip file.

I think the issue might have been that HandleHttpRequest needs to be paired with HandleHttpResponse in order to generate a response to the client. You were making GET requests via the browser, a flowfile with no content was generated and passed to PutFile, but no response was sent back to the client, so a 503 error was generated. As you noted, ListenHTTPRequest doesn’t operate in this manner (it provides an HTTP response immediately), so you no longer have that error. Here is an example HandleHTTPRequest/HandleHTTPResponse article [1] if you want to revisit this.

The stacktrace should clearly explain the issue though, so hopefully this solves your problem.
