We’ll be happy to take a look at what might be happening and see where we can assist.
If possible, could you shoot us an email at productsupport@sketch.com along with the file so that we can conduct some tests on our end to figure out what’s happening?
Cheers
UPDATE NOTE: We have run a few tests and were able to reproduce the same error. We have already escalated this to the team with urgency. As soon as I have an update, I will let you know.
We just released version 100.2 , which incorporates a solution that resolves the problem with the Figma converter. I recommend you update your Sketch version and let me know if the issue remains on your side.
The documents I use for testing only shows errors related to fonts, which we expect due to their nature. However, your specific document is presenting additional errors that may require escalation.
