Error after enabling IAP

[Vi]

I did deploy a Node.js application on GAE Flex.

To handle user access, this app uses OAuth 2.0.

It generally works fine, but if I activate the Identity-Aware Proxy, I get a error:

There was a problem with your request. Error code 9

Do you have any clue about it? Why this happens only with IAP?

Thank your for your support.

Hello 

I did a test implementation of Node.js application using OAuth 2.0 to GAE Flex with IAP enabled. It worked successfully without any error. For your reference, I used this example documentation to implement the application and OAUTH to authenticate users and enabled IAP.

This seems like configuration related problem. Google group is not right place to look for 1-on-1 support. I recommend posting your question on stackoverflow.com where you have access to a large community of enthusiasts and experts to share ideas with and get support from. Please make sure to include all relevant details and error messages which would help the community to troubleshoot.
