when i try to start websocket connection from frontend code,it display an error as unable to upgrade *http.response to websocket websocket: request origin not allowed by Upgrader.CheckOrigin in the server side
to fix it i update the package but it still persist
- `go version`?
- // Create the GraphQL server
srv := handler.NewDefaultServer(graph.NewExecutableSchema(graph.Config{
Resolvers: resolver,
}))
srv.AddTransport(&transport.Websocket{
Upgrader: websocket.Upgrader{

CheckOrigin: func(r *http.Request) bool {
// Replace "http://example.com" with the allowed origin
allowedOrigin := "http://localhost:5173/"
return r.Header.Get("Origin") == allowedOrigin
},
},
})
