Google AppEngine Endpoints Error: Fetching service config failed (status code 404)

I am implementing the steps in the Quickstart.

I did notice another question on this. I double checked that env_variables section in app.yaml has the right values for ENDPOINTS_SERVICE_NAME and ENDPOINTS_SERVICE_VERSION.

../_ah/api/explorer doesn't show any endpoint under 'Services'.

What is this error and how to fix it?

Error log shows:

While using Cloud Endpoint, must make sure the config ID is the same as in app.yaml

gcloud endpoints configs list --service=myapp.appspot.com

Result:

CONFIG_ID     SERVICE_NAME
2018-08-13r0  myapp.appspot.com

In app.yaml

ENDPOINTS_SERVICE_VERSION: 2018-08-13r0

You just need to follow these steps:

  1. Display the service configuration ID by running the following command:

    gcloud endpoints configs list --service=echo-api.endpoints.[PROJECT-ID].cloud.goog

  2. Replace [PROJECT-ID] with your project ID. Do not include the square brackets.

  3. Edit the app.yaml file in the python-docs-samples/appengine/standard/endpoints-frameworks-v2/echo directory, and make the following changes in the env_variables section:

    env_variables:
  # Replace with your endpoints service name.
  ENDPOINTS_SERVICE_NAME: "echo-api.endpoints.[PROJECT-ID].cloud.goog"
  # Replace with the version Id of your uploaded Endpoints service.
  ENDPOINTS_SERVICE_VERSION: "[YOUR-SERVICE-CONFIG-ID]"

  4. Replace [PROJECT-ID] with your project ID and [YOUR-SERVICE-CONFIG-ID] with your service configuration ID from the previous step. Do not include the square brackets. For example:

    env_variables:
  # Replace with your endpoints service name.
  ENDPOINTS_SERVICE_NAME: "echo-api.endpoints.example-project.cloud.goog"
  # Replace with the version Id of your uploaded Endpoints service.
  ENDPOINTS_SERVICE_VERSION: "2016-12-14r1"

You just need to choose one of the options shown on the first command.

I have app call myapp

First show services:

D:\projects\barcode\ebk>gcloud service-management configs list --service=myapp.appspot.com
CONFIG_ID     SERVICE_NAME
2017-06-29r3  myapp.appspot.com
2017-06-29r2  myapp.appspot.com
2017-06-29r1  myapp.appspot.com
2017-06-29r0  myapp.appspot.com

You can see first line in result is 2017-06-29r3 myapp.appspot.com, edit app.yaml:

env_variables:
  # The following values are to be replaced by information from the output of
  # 'gcloud service-management deploy swagger.json' command.
  ENDPOINTS_SERVICE_NAME: myapp.appspot.com
  ENDPOINTS_SERVICE_VERSION: 2017-06-29r3

This works for me

I had the same Exception trace, except mine was a 403. Hope is helpful to others having the same frustration I had.

Exception: Fetching service config failed (status code 403)

I finally found that in my app.yaml it had this from the GIT clone

ENDPOINTS_SERVICE_NAME: echo-api.endpoints.[YOUR-PROJECT-ID].cloud.goog

And the Quickstart only directed me to replace YOUR-PROJECT-ID.

I had to also replace .cloud.goog with .appspot.com

If fetching the service config failed with a 404, then the gcloud service-management deploy step probably didn't work as expected. I would try that step again, making sure that everything is configured correctly, and make sure that the command finishes with no errors.
