I cannot download .xlsx file via swagger UI. But before update it has worked filne. I updated lib for .net wich uptdated Swagger UI from 3.47.1 to 4.12.0. And now i am getting the error "TypeError: e.split is not a function". I have tried add header "Content-Disposition: attachment" and it doesn't work.
I changed media type from "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" to "application/octet-stream" and it works, but i get unknown type of file as well.


Any idea what i can do?

Research direction
Start by reproducing the failure in Swagger UI 4.12.0 with an OpenAPI 3.0.1 response using the XLSX media type, then compare the behavior with version 3.47.1. Done means the XLSX response downloads from the UI without the TypeError and retains the correct file type.
