Can't able to create invoice through REST (Postman testing)

I am new to erpnext. I installed frappe and bench in my server. I want to create an invoice through a php website. So I am testing that endpoint with data shown in the following image. But it’s ending up with the error listed below the image.

Traceback (most recent call last):
