LEX V2 Fulfillment lambda version

Does anybody have experience with the AWS LEX V2 updateBotAlias call in the AWS JavaScript SDK? How do you specify the lambda interface version (codeHookInterfaceVersion)? The lambda clearly has a version 1. It keeps saying:

ValidationException: The specified Lambda function interface version isn't valid. Specify a different interface version and try your request again.

By the way how do you specify the $LATEST?

This is my request:

{
  "botAliasId": "TSTALIASID",
  "botAliasName": "TestBotAlias",
  "botId": "3UR9######",
  "botAliasLocaleSettings": {
    "en_US": {
      "enabled": true,
      "codeHookSpecification": {
        "lambdaCodeHook": {
          "lambdaARN": "arn:aws:lambda:us-east-1:##########93:function:fulfill-lambda",
          "codeHookInterfaceVersion": "1"
        }
      }
    }
  },
  "description": "en_US (Alias)"
}

For me I'm sending:

codeHookSpecification: {
    lambdaCodeHook: {
        codeHookInterfaceVersion: '1.0',
        lambdaARN: botFunctionArn
    }
}

The ARN format ending in :function: is $LATEST. If you want to connect your code hook to a specific version of the lambda function you would use an ARN ending in :function::
