Hello Shahrukh,

Did you want to create a custom app?

This error is shown because you create the app when we create the app we need to set up a local server for this we use ngrok.

I think you didn't properly contact ngrok.

Hey Shahrukh

I think you have successfully installed your custom app.

This error is you showing after the app click or installation? 
If you successfully installed the app then wherever you close your code file then you need to run "ngrok HTTP 80 " command on cmd.
