some error message about running in 3.36

[JadeVane]

I kown it just support 38 and 40 clearly, but from #7, I guess that you are try to learn more about how to run it in 36, I am not sure if you have any plan to develop this extension in 36 which I really hope you to do so, and what I can do is helping to test it in 36 and tell you what you need.

This is what I get from journalctl -f -o cat /usr/bin/gnome-shell after enabling this extension

BTW, the extension works well, but I can't access it from the settings.

[sakithb]

Thanks I will analyze the logs and reply. Sorry for the late reply.

[MahmoudAFarag]

The problem still persists on gnome 3.36, any updates?

[sakithb]

Sorry I didn't really have any time to look in to this issue. My work is clearing up now, so hopefully around tomorrow I will update you.

[sakithb]

Hello, I fixed the above errors and created the pre-release for v18, it should support GNOME 3.36. If there are any furthermore issues, please report here.

[sakithb]

I will close this issue now, If there is some issue with 3.36 support, feel free to re-open.

I met the same error with Ubuntu 20.04.5 + GNOME Shell 3.36.9.

log:

The settings of extension mediacontrols@cliffniff.github.com had an error:

SyntaxError: expected expression, got '?'
