Re: error code question

[Craig Dabelstein]

Thanks for your help. The problem was not including spacer rests for the opening grace notes in the measure counter.

All the best,

Craig

Most likely you somewhere apply a custom-function with
(ly:grob-array->list (ly:grob-object left-bound
...
in the code.

ly:grob-object returns an empty list in your case, thus
ly:grob-array->list expecting a grob-array complains. The error
message doesn't return the second argument with which ly:grob-object
is called, so I cn't say more yet.

Find and check this function for typos and/or c/p-errors.

Find where this function is applied in your music, boil it down to a
minimal example and post it here.
Otherwise noone can say why it happens.
