I got the {"success":true,"info":"WhatsApp API v1.1.2 | V⦿iceflow | 2023","status":"healthy","error":null} message, however I don´t get the URL to validate my webhook, the only thing I get in the Webview as a URL address is "/".

Getting the same, both with the fork of the repl and locally with localtunnel.

I have the same problem. Does anyone know the solution? I can't get the URL; it just shows a slash ("/") for me.
