1. gcloud components update 2. Change version for appengine-api-1.0-sdk from 1.9.30 to 1.9.49 3. gcloud deploy openapi.json, because the sample sends metrics to the endpoints service 4. export ENDPOINTS_SERVICE_NAME=echo-api-flex.endpoints.[YOUR_PROJECT_ID].cloud.goog Others who see this issue: 1. gcloud components update 2. git pull (Get the latest code sample, because it's changed frequently) 3.
