Some code called array.toString() on a Uint8Array instance

[deisi]

According to my gnome-shell, the addon will soonish break due to an upcoming change in gjs.
I find:

Sep 14 13:37:26 mtop gnome-shell[1490]: Some code called array.toString() on a Uint8Array instance. Previously this would have interpreted the bytes of the array as a string, but that is nonstandard. In the future this will return the bytes as comma-separated digits. For the time being, the old behavior has been preserved, but please fix your code anyway to explicitly call ByteArray.toString(array).
                                        (Note that array.toString() may have been called implicitly.)
