\harmonicByFret takes a possibly complex music expression and returns a
definitely complex music expression.
You cannot add a textscript with ^... to a complex music expression.
You can get by here by writing
\harmonicByFret #sfrt {#note ^\markup { \center-align \teeny \concat {< #hfrt >
}}}
This is not really pretty and works by first sweeping up #note and
^markup ... into a sequential music expression and combining them while
doing so, then letting \harmonicByFret operate on that combined
expression.
If #note is already a complex music expression rather than a single note
or rest (with possible post-events), then this will still fail. But it
does not seem like this case would make a lot of sense anyway.
