I’m setting up Cloud Endpoints Framework for java in my GCP App Engine project, following the official documentation:

• https://cloud.google.com/endpoints/docs/frameworks/java/set-up-environment
• https://cloud.google.com/endpoints/docs/frameworks/java/using-guice
• https://cloud.google.com/endpoints/docs/frameworks/java/adding-api-management

The whole thing works, but when I look at the logs, I can see the error below.

It seems that Guice is triggering it but I’ve no idea what’s happening. Am I missing something?

I get the error both locally and when deployed in App Engine

I use the appengine-maven-plugin

mvn clean package

mvn appengine:deploy or locally: mvn appengine:run

For deploying cloud endpoints:

mvn endpoints-framework:openApiDocs

gcloud --project=myproject endpoints services deploy target/openapi-docs/openapi.json

I use the Google API Explorer to test my API: https://apis-explorer.appspot.com/apis-explorer/?base=http://localhost:8080/_ah/api#p/

EDIT:

I get the error as soon as I deploy the openapi.json file. Before deploying it, I don’t get the error locally. After deploying it, I get the error both locally and in App Engine.

I have Google Cloud SDK 280.0.0 and app-engine-java 1.9.78
