Hi @shivaadapa 

I would suggest you to achieve this by using flow designer. Its very simple and easy to configure. You can use inbound email as your trigger and in action you can create incident record as per your requirement. 

Else, you can share your code here of calling script include from inbound email action. I will help you for same as well.

If this solution resolves your query, kindly mark it as the accepted solution and give it a thumbs up.
