Hi @yangchangqu. Thank you for reporting this bug. Parts of this issue might be duplicates of #2317, #2479, and #1983.
One suggestion as a workaround is to run turf.truncate() on your polygons to address a precision issue in the polygon-clipping library. Can you please try that and let us know if it helps?
@smallsaucepan thank you very much for your reply, your suggestion perfectly solved the problem !
