Simply you can look into the log in the Output window. The actual error can be seen there in my case, I missed adding HTTP action on top of a methods

When we add phpdoc in API creation it adds like:

/**
    * @param $orderId
    * @param $mailId
    * @return mixed
*/

You need to replace the above code with:

/**
    * @param int $orderId
    * @param mixed $mailId
    * @return mixed
*/
