The reason why it is not accepted is because the move counter is missing:
Given:
rnbakabnr/9/1c5c1/p1p1p1p1p/9/9/P1P1P1P1P/1C5C1/9/RNBAKABNR w
Expected:
rnbakabnr/9/1c5c1/p1p1p1p1p/9/9/P1P1P1P1P/1C5C1/9/RNBAKABNR w - - 0 1
However, in the current Fairy-Stockfish master this has already been fixed, and both given FEN are treated as valid:
I will be releasing a new ffish.js version shortly so this change can take effect.
I tried to copy and paste FEN from WinBoard / XBoard and also from https://www.chessdb.cn/query_en/ but it doesn’t work.
