In conditional plea appeals, is an error harmless when (1) the error did not affect the defendant's choice to plead guilty; or (2) the error did not affect a count of conviction?

QUESTION PRESENTED Under Federal Rule of Criminal Procedure 11(a)(2), a defendant may enter a guilty plea conditioned on the right to appeal an adverse pretrial ruling.
