First of all, I'd like to use Cryptpad with Odoo, but that is another story.

I have successfully set up etherpad lite on our server and hooked it up with Odoo 12 CE. I have activated the necessary modules, and the etherpads are showing up in Odoo. But:

Odoo transmits the username “undefined” to etherpad, and thus “undefined” shows up as the current user in the editor. I can track down the iframe URL of the pad given as “https://[ourserver]/p/intra-note.note-[random-characters]?showChat=false&userName=undefined”

Is there any quick fix?
