Issue with exception handling

[knit-pay]

I am trying to call the createPaymentRequest function with an amount less than 9 INR, instead of giving a proper error message, it's giving an arbitrary error message "Invalid request" Kindly fix it. getting the same issue with other errors like invalid phone, invalid email, etc.
On the below line of code, we are getting the correct error message in $response_obj variable but in the exception which we are getting in the try/catch block, it's a wrong error message.

instamojo-php/src/Utilities.php

Line 97 in 5856461

$message = isset($response_obj['reason']) ? $response_obj['reason'] :$message;
