Cloudformation giving error "Requires capabilities : [CAPABILITY_AUTO_EXPAND]"

Question

I am trying to implement Continuous Deployment for my .net core app. When lambda function is invoked, I'am trying to create a cloudformation to spin up the resources. But getting error:

Creating Cloud Formation stack: gateway-api-uat-stack Failed to create stack: gateway-api-uat-stack. Reason: Detailed Message: Requires capabilities : [CAPABILITY_AUTO_EXPAND] (Service: AmazonCloudFormation; Status Code: 400; Error Code: InsufficientCapabilitiesException; Request ID: 4779587c-2a17-11e9-a093-c1704a1bf953) Status Code: 400 Error Code: InsufficientCapabilitiesException

Deleting Cloud Formation stack: gateway-api-uat-stack Cloud Formation stack: gateway-api-uat-stack deleted successfully Finished: FAILURE

This is my serverless.template file

  "Type" : "AWS::Serverless::Function",
  "Properties": {
    "Handler": "Handler-name",
    "Runtime": "dotnetcore2.0",

    "Role": null,
    "Policies": [ "AWSLambdaFullAccess" ],
    "Environment" : {
      "Variables" : {
      }
    },
    "Events": {
      "ProxyResource": {
        "Type": "Api",
        "Properties": {
          "Path": "/{proxy+}",
          "Method": "ANY"
        }
      },
          "RootResource": {
        "Type": "Api",
        "Properties": {
          "Path": "/",
          "Method": "ANY"
        }
      }
    }
  }

}

}

When using the Transform: AWS::Serverless-2016-10-31, Cloudformation requires the CAPABILITY_AUTO_EXPAND.

If you're deploying from the command line, add --capabilities CAPABILITY_AUTO_EXPAND to your create / deploy command.
