As part of a bigger script, I’m trying to script export of a variable font but can’t get it to work.
File "GlyphsApp/GlyphsApp/__init__.py", line 4279, in __Font_Export__ AttributeError: 'GlyphsFileFormatVariationFonts' object has no attribute 'writeVARTables_error_'
File "GlyphsApp/GlyphsApp/__init__.py", line 4222, in __Instance_Export__ KeyError: "The font format is not supported: variable (only 'OTF' and 'TTF')"
Using instance.generate() for other formats, I can control export path, etc. which is essential for the use of this script.
Variable font export from the normal Export dialog works fine.
Thankful for any help,
