Hi.
I'm using Moodle 3.9.1+
I have no additional theme plugins installed.
I'm build preset file with https://github.com/moodle/moodle/tree/master/theme/boost/cli script for lux bootsatch theme: https://bootswatch.com/lux/.
When I add this file in presets list in admin panel and select as active, I see this error.
Help me, please.
