Connector Throws Serialization Exception When Used with API Kit Router #30

Closed arifcse019 closed 7 years ago

arifcse019 commented 8 years ago

I am using mule 3.8.0 CE. I am getting the following exception when trying to use Facebook Connector with API Kit Router

`ERROR 2016-10-25 14:39:56,699 [[facebook-connector-test].httpListenerConfig.worker.01] org.mule.exception.DefaultMessagingExceptionStrategy:

`

However, if I replace the <apikit:router config-ref="Router" doc:name="APIkit Router"/> in main flow i.e. "facebook-demo", with a flowref like <flow-ref name="get:/facebook-user-posts:Router" doc:name="get:/facebook-user-posts:Router"/>, then the app runs through.

Please suggest.

The issue was with the RAML file where it said

...... responses: 200: body: application/json ............

During the OAuth dance, the endpoint returns null payload and then redirects the user to the callback. Hence the java.io.NotSerializableException caused at org.mule.raml.implv1.model.MimeTypeImpl.

The correct RAML should replace application/json with nil
