I'm trying to update attachment metadata using the default rest API, in the documentation it says it supports the meta field. But when I'm trying to update the artist or album field for an audio file using REST API, it doesn't save the data.

Payload:

{
    meta: {artist: "Mons"}
    artist: "Mons"
    title: "Hello world"
}

Also tried with:

{
    meta: _wp_attachment_metadata: { {artist: "Mons"} }
    artist: "Mons"
    title: "Hello world"
}

Endpont: /wp-json/api/v2/media/__ID__/

Here title gets updated but artist doesn't.
