I'm trying to deploy my serverless app on local stack but Invalid type parameter for selectionPattern error is being thrown. Below is the complete error and serverless.yml Error: > ApiGatewayMethodActionPost (Parameter validation failed:; Invalid type for parameter selectionPattern, value: 200, type: <class 'int'>, valid types: <class 'str'>) serverless.yml ``` events: - http: path: /action method: POST iamRole: arn:aws:iam::xxxxxxxxxxxx:role/someRole action: StartSyncExecution request: template: application/json: | { "stateMachineArn":"arn:aws:states:'us-west-2':xxxxxxxxxxxx:stateMachine:someMachine", "input": "$util.escapeJavaScript($input.json('$'))" } response: template: application/json: | $input.path('$.output') ``` I was checking serverless-step-function code where selectionPattern is defined as integer and not string. Following is the link to the code: [code](https://github.com/serverless-operations/serverless-step-functions/blob/8772ae7d8662b80bc584342cc39e48fc6f9c6a53/lib/deploy/events/apiGateway/methods.js#L199)
