Serverless "Post Function" doesn't work with AWS Lambda

[DeeGeeMan]

Summary

The Serverless Function plugin "post-function" plugin doesn't work with an AWS Lambda plugin.

Steps To Reproduce

1. Create an AWS Lambda function and assign it to a service
2. Create a Serverless Functions post-function using the example given in the documentation
3. Send a request to your new service without the x-custom-auth in the header

Note: the request is executed even without the x-custom-auth in the header. However, the pre-function works as expected.

Additional Details & Logs

• Kong version (0.14.0)

This is expected behavior due to the fact that AWS Lambda short-circuits the normal proxying lifecycle. Plugins with a lower priority that AWS Lambda will not execute in the current design of Kong.

Long-term fix is likely to be supporting a true content phase handler for plugins, rather than having to return out of the access phase. Because we leverage proxy_pass as the content handler this is likely to involve a bit of redirection internally.
