What were you trying to accomplish?
Add a function to handle multiple http methods using the ApiGatewayResolver:

app = ApiGatewayResolver(proxy_type=ProxyEventType.APIGatewayProxyEventV2)
@app.route("/", method=["GET", "PUT", "POST"])
def event_handler():
    return {"path_received": app.current_event.path, "method": app.current_event.http_method}

Expected Behavior

It should be supported to pass a list of methods to ApiGatewayResolver.route, the same way it is supported for the Router.route method.

Current Behavior

Exception is thrown.
