NiFi - Need help with HandleHttp processors

[#1]

I want to handle custom http request with response. Response should be a content from given file. I'm using FetchFile But it's not working.

Connecting to 10.102.0.216:8082... connected. HTTP request sent, awaiting response... That's it. Port and IP is correct. Here is my Flow:

[#2]

Are you receiving errors on the bulletins for HandleHttpRequest or Response?

Could you specify how the desired file is being mapped from your request to the Fetch File processor? Configuration of your processors or a template would be most helpful.

Thanks!
