TypeError: Cannot read property 'addAmazonSignatureV4' of undefined

[Vikas-kum]

I am getting this error when using this plugin with artillery.

My script.yaml looks like this:

config:
  # this hostname will be used as a prefix for each URI in the flow unless a complete URI is specified
  plugins:
    - "aws-sigv4":
        "serviceName": "execute-api"
    - "expect" : {}
  

  target: "<AWS api gateway host>"
  phases:
    -
      duration: 5 # 5 seocnds
      arrivalRate: 2 # 2 new veirtual users coming every second
      name: Warm up phase




scenarios:

  -
    beforeRequest: addAmazonSignatureV4
    flow:
      - post:
          url: /"{{ $processEnvironment.STAGE }}"/getId
          # request body goes in json
          json:
            input: "abc"
          
          expect:
            - statusCode: 200
