[Bug]: REST Tool giving error

🐞 Bug Summary

I have created a simple HTTP REST Tool with a public API for the below curl. Curl is working from the same machine. But the tool is not giving response.

Curl:

curl --location 'https://newsapi.org/v2/top-headlines?country=us&apiKey=8697c4b48d2940b895b4b51064ee67a6'

Tool:

Error:

Refactored parameter passing to use the inputSchema field (via both Schema Builder and JSON Input), instead of embedding parameters in the URL. However, the parameters dictionary is arriving empty in the backend, causing tool invocation to fail due to missing inputs.
