Include credentials to pass cookies in request header

[Moatez]

Hi! ,

I have been trying to allow crendetials in my request so i can pass my cookie with my fetch request and already configured my backend ( configured with express session ) with origin as https://app.powerbi.com which is wrong since origin is null inside a sandbox ( i tried to set origin as * include wont work that way )  , Do you guys have any idea how to do this?

Fetch request inside my custom visual :

public fetch = () => {  
     fetch(
      "http://localhost:3000/api/v1/test",
      {
        method: "GET",
        credentials: "include",   
       
      }
    )
      .then((response) => {
        return response.json();
      })
      .then((test) => console.log(test));
  };

Backend cors :

server.use(
  cors({
    origin: '*',
    credentials: true,
  }),
);
