App Engine Rpc Discovery Doc

I've been using app engine for Java with cloud endpoints to create a REST api and have suddenly run into this error: WARNING: No discovery doc for API hylytit version v1 in rpc for

Solution 1:

Willma, did you update your App Engine Eclipse Plugin or SDK recently? If you did, try also update the Google Plugin for Eclipse. Those plugins need to be in-sync for Google Cloud Endpoint Client library generation to work properly on Eclipse. Once you update both plugins, the client library generation should work. Deploy the application to App Engine again, then you should be able to verify again based on the URL you showed above.

Solution 2:

Make sure you have valid return types. I was facing the same issue after using an invalid return type (boolean) for an ApiMethod. Note that GPE docs say, "In the Endpoint methods, the return value type cannot be simple type such as String or int. The return value needs to be a POJO, an array or a Collection."
