I am using "userData" in the window.botpressWebChat.init as per the documentation to get the user information like name, email, etc to the botpress. I have followed all the steps explained in the documentation https://botpress.com/docs/cloud/channels/webchat/#send-user-data-from-your-website-to-botpress . It works some times.But most times it doesn't. But it just gives an empty {} even I passed data to userData.
