How to use multiple query string authorizers with aws_apigatewayv2_authorizer

Question

I´m using a custom lambda authorizer on my API Gateway Websocket, and I'd like to attach another query string authorizer, but I'm facing some errors and I didn't find any example.

The implementation of the authorizer:

```
resource "aws_apigatewayv2_authorizer" "authorizer" {
  api_id                   = aws_apigatewayv2_api.api_gateway_websocket.id
  authorizer_type          = "REQUEST"
  authorizer_uri           = var.lambda_authorizer_uri
  identity_sources         = ["route.request.querystring.authorization", "route.request.querystring.route"]
  name                     = var.lambda_authorizer_name
  authorizer_credentials_arn = var.authorizer_credentials_arn
}
```

and my connect:

```
resource "aws_apigatewayv2_route" "ConnectRoute" {
  api_id         = aws_apigatewayv2_api.api_gateway_websocket.id
  route_key      = "$connect"
  operation_name = "ConnectRoute"
  authorization_type  = "CUSTOM"
  authorizer_id  = aws_apigatewayv2_authorizer.authorizer.id
  depends_on = [
   aws_apigatewayv2_authorizer.authorizer
  ]
}
```

Is there anyone who have an example of how to use multiple query string authorizers, or any idea of how can I implement this? Thank you so much.

Answer

Could you suggest what is the error message you are seeing?

I was able to add two query strings successfully in Websocket API authorizer identity sources without any issue on API Gateway console.
If possible, could you try adding from console and see if the error persists?

If it works on console as expected and issue is only while deploying with terraform, I would recommend reaching out to terraform support and they should be able suggest the syntax for implementation of the use case.

Feel free to open a premium support case https://docs.aws.amazon.com/awssupport/latest/user/case-management.html and we will be happy to help you troubleshoot the issue.
