TypeError: l['$adagio-location'] is undefined

[jenia0jenia]

I have an error in my embed .mxl

[error] TypeError: l['$adagio-location'] is undefined

and here is link (SECOND frame)... http://elib.pl.spb.ru/search_result_full?data=eyJ0eXBlX3MiOiBbIjEyMDAwIl0sICJ0ZXJtIjogWyJkZjBmZmFlZDc4NDBmZjQzYzhiYzJhYmQxOTRhYTA0MiJdfQ==#nota

But it is absolutely correct when I import .mxl to flat.io https://flat.io/score/65573383c1ff184a0775b637-stehe-still

firefox 119.0.1 x64

(in chrome I have another error [Vue warn]: Error in 5: "TypeError: Cannot read properties of undefined (reading 'timePos')")
