Invalid GET /me/player/currently-playing response document

[Hoto-Cocoa]

At Spotify API document, Get Currently Playing Track API response document is not showing expected data, It shows template engine code. I confirmed other status codes than 200 are working as expected.

I checked some other API response document works as expected but I didn't checked all of them.

That shows text '#/components/responses/OneCurrentlyPlayingTrack' instead of response format document that expected.
