How to load a remote extension in geckoview?

[baseplate-admin]

Hi, i have this following kotlin code

  sRuntime.getWebExtensionController().ensureBuiltIn(
            EXTENSION_LOCATION,
            "uBlock0@raymondhill.net"
        ).accept(
            { extension ->
                // Use Log to print information about the installed extension
                Log.i("MessageDelegate", "Extension installed: " + extension)
            },
            { e ->
                // Handle error if registering the WebExtension fails
                Log.e("MessageDelegate", "Error registering WebExtension", e)
            }
        )

and this location.

But this doesn't register and the log has some weird things in it:
