The http code status returned by the backend is not taken into account in the websocket response

Hi,

We are Using Api gateway Websocket (route $connect ) with the following configurations :

• Integration type: Lambda Function
• Use Lambda Proxy integration: False
• Use of Custom Request Templates
• Route Integration Response Key: $default

Behavior :

Backend (lambda) response : { "statusCode": 401}
Websocket Response status code: 101. (should be 401 like lambda response )

Question:

How can I configure the Websocket Route response to match the backend response?

I really appreciate any help you can provide.
