attach lambda authorizer to http API

Question

Hi team,

I want to create an API gw lambda authorizer and attach it to the HTTP API

this is the piece of code I did :

```
// create api gw authorizer
    const apiGwAuthorizer = new HttpLambdaAuthorizer(
      "ApiGwLambdaAuthorizer",
      myLambdaFuncAuth,
      {
        responseTypes: [HttpLambdaResponseType.SIMPLE], 
        identitySource: ["$request.header.my-header"],
        resultsCacheTtl: Duration.seconds(300),
      }
    );

//attach the authorizer to the ANY route
    myhttpapi.addRoutes({
      integration: new HttpLambdaIntegration(
        "authorizer-lambda-integration",
        authorizerLambda
      ),
      path: "/ANY /{proxy+}",
      authorizer: apiGwAuthorizer ,
    });
```

but when I deploy the CDK this authorizer created but it's not associated with the API GW

the API GW is passed as parameter from other stack in this stack

Not sure what I miss here, is it because the route 'ANY /{proxy+}' already exists?

Answer

Not sure, but try doing it the other way around (if you want to split into two stacks). Create the Lambda function in one stack. In the API GW stack, attach the authorizer to the right routes.
