844 -[OTTableWriter getOverflowErrorRecord:]

I have had no trouble exporting this variable font, but after kerning it I have been receiving this error message and can no longer export it. I poked around a little but I can’t understand any of the answers I’ve found. I appreciate any and all assistance!

If you add more kerning the space in the GPOS table will run out. You can make some extra room by using the Use Extension Kerning parameter in the font custom parameters.

Thank you Georg, I applied that and deleted a few kerning pairs and it worked!
