• Wait for the script to finish and login into the admin portal and confirm that the backend has the correct mapping rules/methods mapped.
• Promote

oc apply -f - <<EOF
---
apiVersion: capabilities.3scale.net/v1beta1
kind: ProxyConfigPromote
metadata:
  name: product1-v1-production
  namespace: 3scale-test
  annotations:
    "insecure_skip_verify": "true"
spec:
  productCRName: product1-cr
  production: true
  deleteCR: true
EOF

• Change the mapping rule/methods in the BackendCR as follow

spec:
  mappingRules:
    - httpMethod: GET
      increment: 1
      last: true
      metricMethodRef: GET_two
      pattern: /
    - httpMethod: POST
      increment: 1
      metricMethodRef: hits
      pattern: /
  methods:
    GET_two:
      description: Number of API hits
      friendlyName: GET_two
  metrics:
    hits:
      description: Number of API hits
      friendlyName: Hits
      unit: hit
  name: backend1
  privateBaseURL: 'http://httpbin.httpbin.svc:8080'
  systemName: backend1

• Now you should see the error method is used by the latest gateway configuration, it will be removed from 3scale only once the promotion without the mapping rule that uses the deleted method is done in BackendCR status
• Visit the portal again and confirm that the mapping rules has changed to GET_two method
• Promote again

oc apply -f - <<EOF
---
apiVersion: capabilities.3scale.net/v1beta1

  name: product1-v1-production
  namespace: 3scale-test
  annotations:
    "insecure_skip_verify": "true"
spec:
  productCRName: product1-cr
  production: true
  deleteCR: true
EOF

• It may take a while but eventually the error will go away.
