What is expected?

Successful validation

Context

I'm attempting to create a bridge between my Sonos set up at home and my Funkwhale installation. I've already got a semi-working set up using Funkwhale's implementation of the Subsonic API however Funkwhale's API appears to be a better API to use, especially as the Subsonic API lacks pagination.

However, the swagger.yml file (and its dependencies) have incorrect JSON pointers, causing errors:

Example:

- $ref: "./api/definitions.yml#OAuthApplication"

Should be:

- $ref: "./api/definitions.yml#/OAuthApplication"

Funkwhale version(s) affected: Latest?
