I had set it to `audio/opus` which does not exist.

> An "Ogg Opus file" consists of one or more sequentially multiplexed
   segments, each containing exactly one Ogg Opus stream.  The
   RECOMMENDED mime-type for Ogg Opus files is "audio/ogg".

>    The RECOMMENDED filename extension for Ogg Opus files is '.opus'.

> When Opus is concurrently multiplexed with other streams in an Ogg
   container, one SHOULD use one of the "audio/ogg", "video/ogg", or
   "application/ogg" mime-types, as defined in [[RFC5334](https://datatracker.ietf.org/doc/html/rfc5334)].
