Create methods under / using CF for API Gateway

问题

How do I create methods under API Gateway's root / folder using CF? So for example I have a Gateway that looks like the following:

/ OPTIONS POST

However when trying to do that with CF I get: Resource's path part only allow a-zA-Z0-9._- and curly braces at the beginning and the end. So my PathPart is the offending line.

  ApiGate:
    Type: AWS::ApiGateway::Resource
    Properties:
      ParentId: !GetAtt 
        - ApiGateApi
        - RootResourceId
      PathPart: '{/}'
      RestApiId: !Ref ApiGateApi

I can change the PathPart to something else but then it creates it as a child object under / which is what I don't want.

Turns out after adding the following to my AWS::ApiGateway::Method it works now.

  MyMethodOPTIONS:
    Type: 'AWS::ApiGateway::Method'
    Properties:
      ResourceId: !GetAtt MyRestApi.RootResourceId

Here is more context into my Template:

  ApiGatewayMethodOPTIONS:
    Type: 'AWS::ApiGateway::Method'
    Properties:
      ResourceId: !GetAtt ApiGatewayRestApi.RootResourceId
      RestApiId: !Ref ApiGatewayRestApi
      AuthorizationType: NONE
      HttpMethod: OPTIONS
