I'm trying to deploy a sample serverless stack using the serverless-localstack plugin but I'm getting this error

localstack_1  | 2021-01-22T22:20:42:INFO:localstack.utils.cloudformation.template_deployer: Unable to create stack uploadToS3-local: Parameter validation failed:
localstack_1  | Invalid type for parameter integrationHttpMethod, value: None, type: <class 'NoneType'>, valid types: <class 'str'>
localstack_1  | Invalid type for parameter uri, value: None, type: <class 'NoneType'>, valid types: <class 'str'>

My serverless file:

service: uploadToS3

frameworkVersion: ">=1.1.0"

custom:
  bucket: tutorial
  localstack:
    stages:
      - local
    host: http://localhost
    endpointFile: localstack_endpoints.json
    lambda:
      mountCode: True
provider:
  name: aws
  runtime: nodejs10.x
  region: us-east-1
  deploymentBucket:

  uploadImageToS3:

    events:

          path: /get
          method: GET
          cors: true

docker-compose:

services:
  localstack:
    image: localstack/localstack:latest
    ports:
      - "4566-4599:4566-4599"
      - "8080:8080"

    volumes:
      - "${TMPDIR:-/tmp/localstack}:/tmp/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

When I deploy my lambda without cors everything works fine, but with cors: true I got the above error
