Google Cloud Endpoints + Firebase Auth: method_info is not set

Question

So I am running the sample code provided by Google:

package com.neat.backend;
/**
 * An endpoint class we are exposing
 */
@Api(
        name = \"myApi\",
           


        

Answer 1

@Kevendra's answer highlights that this issue can be caused if an openapi.json file is missing a reference to the endpoint API method. Firebase may be using this to reference and discover the API method.

From the Google OpenAPI Overview:

Basic structure of an OpenAPI document:

An OpenAPI document describes the surface of your REST API, and defines information such as:

The name and description of the API. The individual endpoints (paths) in the API. How the callers are authenticated.

Follow these steps to regenerate and deploy the openapi.json file:

---

generate:

$ mvn clean package endpoints-framework:openApiDocs -DskipTests

• mvn clean - run a Maven goal to clean your project. package - compile and package it
• endpoints-framework:openApiDocs generate OpenAPI documents. This will generate the openapi.json file at the location: target/openapi-docs/openapi.json- see generating and deploying an api configuration.
• -DskipTests skips running any tests, to avoid any test failure due to the openapi.json not yet being generated

---

deploy:

(As a precaution you can first validate the project ID returned from the following command to make sure that the service isn't created in the wrong project - gcloud config list project)

  $ gcloud endpoints services deploy target/openapi-docs/openapi.json

Deploys the openapi.json file from its generated location (in the 'generate' step above). See the Google docs on Deploying the OpenAPI document
