Xibo Player error

I’m running the latest version of Xibo 1.8.3 using Docker. I have a layout running in one player under Windows 10 however it gives me the error" Unable to create new font object: Not a valid media node type: font". Any suggestions for how to fix this?

You could try ‘verify all’ on the modules page, which should rebuild fonts and player will download them again.

Tried that. Player is still getting Unable to create new font object: Not a valid media node type: font
