Fail to generate entry in Themes->Appearance

[pasmon79]

I installed pywal and oomox on my ubuntu 20.04. I have gnome tweak extensions enabled along with dash to panel. pywal successfully changes the theme for terminal command but fails to generate entry in Tweaks-?Appearance.

Here is a custom output

I] image: Using image 5.jpg. [I] theme: Set theme to _home_quanta_Clouds_GoogleDrive_Wallpaper_Combined_5_jpg_dark_None_None_1.1.0.json. [I] colors: Found cached colorscheme. [I] sequences: Set terminal colors.I] export: Exported all files. [I] export: Exported all user files. [I] reload: Reloaded environment.
