Hi @Ibad_Laskar,

Thanks for sharing this question!

The error might be related to the response your code is getting which might be empty or not a valid JSON format.

You can add the try-except block to catch the errors that might be causing the code to break.

The latest error is suggesting that there’s no key named “input” in your json file. You do a print statement to inspect the entire json so you can see which key to use.
