Default validator being created

[chippyash]

Although I have specified a request validator (using FN::ImportValue), serverless deploy is still creating a default request validator for the stack. Checking the .serverless/cloudformation-template-update-stack.json I can see it declared as a resource, but it is never referenced anywhere else in stack spec.

Is this predicted behaviour or am I missing something?

serverless V3.0.0

provider:
  apiGateway:
    restApiId: ${self:custom.environment.apiGateway.restApiId}
    restApiRootResourceId: ${self:custom.environment.apiGateway.restApiRootResourceId}
...
plugins:
  - serverless-iam-roles-per-function
  - serverless-plugin-log-subscription
  - serverless-plugin-scripts
  - serverless-reqvalidator-plugin
...
functions:
  plan:
    handler: ./bin/xxx
    events:
      - http:
          method: put
          path: aum/xxx
          reqValidatorName:
            Fn::ImportValue: 'apiGwRequestValidateAll'
          request:
            schemas:
              application/json: ${file(serverless/schema/xxx.json)}
            parameters:
              headers:
                x-context-id:
                  required: false
                  mappedValue: context.requestId

@chippyash thanks for opening the issue. Can you specify where apiGwRequestValidateAll is ref from? I don not see any more detail in the provided file

@RafPe That is a reference to an externally created request validator created in another stack. As per your documentation. That works fine btw.

I have a workaround for this at the moment which involves using the serverless-plugin-scripts plugin

custom:
  scripts:
    hooks:
      'after:package:finalize': bash ./scripts/remove-request-validator.sh

the script

#!/usr/bin/env bash
echo "Removing service default request validator"
cat .serverless/serverless-state.json  \
  | jq 'del(.service.provider.compiledCloudFormationTemplate.Resources.ApiGatewayMystackRequestValidator)' \
  > ./state.json
rm .serverless/serverless-state.json
mv ./state.json .serverless/serverless-state.json

cat .serverless/cloudformation-template-update-stack.json  \
  | jq 'del(.Resources.ApiGatewayMystackRequestValidator)' \
  > ./stack.json
rm .serverless/cloudformation-template-update-stack.json
mv ./stack.json .serverless/cloudformation-template-update-stack.json

Not particularly elegant, but it works! If we could get the same functionality into your plugin with perhaps a flag in the custom settings to switch it on/off, that would be marvellous. It would only need to remove the default request validator IF there was nothing referencing it.
