Version

1.49.1

Steps to reproduce

Code_3OaThBCe03.mp4

    // Set up WebSocket interception before clicking Update Device
    await page.routeWebSocket(/.+\/v2/, async route => {
      console.log('routeWebSocket entered');

      const server = route.connectToServer(); // Connect to the actual server
      console.log('Server message: routeWebSocket');

      // Messages from page to server are forwarded automatically
      // We only need to handle server-to-page messages that need modification
      server.onMessage(message => {
        const msgObj = JSON.parse(message);
        console.log('Server message:', message);

        // Check if this is a device status message that needs modification
        if (msgObj?.payload?.data?.DeviceChanged?.DevStatus === 'Disconnected') {
          msgObj.payload.data.DeviceChanged.DevStatus = 'Connected';
          console.log('Modified to:', JSON.stringify(msgObj));
          message = JSON.stringify(msgObj);
        }
        route.send(message);// Send either modified or original message
      });
    });

Expected behavior

It should work regardless of the closed Browser window.

Actual behavior

routeWebSocket fails to intercept the ws. Please check the screencast attached.
