In a tournament I broadcasted, a player made an illegal move which was not seen by the other player (they had very little time and were playing fast). The second player made a move, which by the FIDE rules makes the illegal move permanent and part of the game.

DGT LiveChess correctly puts that move in the PGN, but Lichess Broadcaster refuses to upload the game and errors out with "PGN Error: No move found"
