When setting up an HttpApi from api-gatewayv2, you can specify in corsPreflight param the allowed HTTP methods for CORS. This requires to specify an array of supported HTTP methods from enum HttpMethod.

With code example listed below, cdk deploy throws an error saying Method ANY is not supported when deploying the stack.

Reproduction Steps

1. cdk init sample project
2. Declare HttpApi via code snippet below
3. run cdk deploy --trace --verbose
4. Inspect trace

import * as apiv2 from "@aws-cdk/aws-apigatewayv2";

const api = new apiv2.HttpApi(this, "SimpleApi", {
      corsPreflight:{
        allowHeaders: ["authorization", "x-id-token", "content-type"],
        allowOrigins: ["http://localhost:3000",],
        allowMethods: [HttpMethod.ANY],
        allowCredentials: false
      }
})
