API name with .php calling from WSO2 API manager ISSUE

Question

I am using wso2 API manager 1.7. and need to publish an API written in php. It's endpoint url is coming with .php aslo. But when I publish that API and call it via APIM, it never give any response. I noticed following exception in the carbon log. If I try with directly with the url, API gives correct response. This is a get request and I'm passing url parameters.

Can you please help me how to solve this issue.

API URL : <host>/api/testApi.php

This error is coming when the content body is built. Make sure you are setting the correct content-type header and make sure the relevant Message Builder is enabled in axis2.xml
