Fail to render Japanese fonts

[hamano]

Japanese pdf is not rendered nextcloud 28 clean installation. A blank page is displayed.
The cause is that some static files, including the bcmap file, have not been retrieved.

The following files can be successfully retrieved without authentication. (apache responds 200)

• https://FQDN/apps/files_pdfviewer/js/pdfjs/build/pdf.js
• https://FQDN/apps/files_pdfviewer/js/pdfjs/web/viewer.js

The following file is not found.(apache responds 404)

• https://FQDN/apps/files_pdfviewer/js/pdfjs/web/cmaps/Adobe-Japan1-UCS2.bcmap
• https://FQDN/apps/files_pdfviewer/js/pdfjs/web/locale/locale.properties

I seem to have a problem with static file routing.
Any advice on how to correct this would be appreciated.

When the requested address can be accessed successfully, the problem is solved.

But this is only a temporary solution.
