Cannot import m3u8 playlist (docker arm64)

[niawag]

Hi and thanks for this great app, I love the jukebox mode !

I'm trying to import a m3u8 playlist and it always end up with "0 playlist(s) created - invalid content-type "application/x-mpegurl""
Here is a part of the playlist I want to import:

/music/__tmp/Babylon Circus/State of Emergency/01.Monster.m4a
/music/__tmp/Babylon Circus/State of Emergency/02.Cuckoo.m4a
/music/__tmp/Babylon Circus/State of Emergency/03.Dancing Girl.m4a
/music/__tmp/Babylon Circus/State of Emergency/04.Les Oiseaux de passage.m4a
/music/__tmp/Babylon Circus/State of Emergency/05.Rio Grande.m4a
/music/__tmp/Babylon Circus/State of Emergency/06.State of Emergency.m4a
/music/__tmp/Babylon Circus/State of Emergency/07.Degeneration.m4a
/music/__tmp/Babylon Circus/State of Emergency/08.Fallin.m4a
/music/__tmp/Babylon Circus/State of Emergency/09.Tu n'ecoutes meme pas.m4a
/music/__tmp/Babylon Circus/State of Emergency/10.The Partisan.m4a
/music/__tmp/Babylon Circus/State of Emergency/11.Easy.m4a
/music/__tmp/Babylon Circus/State of Emergency/12.Fire Drill.m4a
/music/__tmp/Babylon Circus/State of Emergency/13.Lettre Ouverte.m4a
/music/__tmp/Baxter Dury/The Night Chancers/01.I'm Not Your Dog.m4a
/music/__tmp/Baxter Dury/The Night Chancers/02.Slumlord.m4a
/music/__tmp/Baxter Dury/The Night Chancers/03.Saliva Hog.m4a
/music/__tmp/Baxter Dury/The Night Chancers/04.Samurai.m4a
/music/__tmp/Baxter Dury/The Night Chancers/05.Sleep People.m4a
/music/__tmp/Baxter Dury/The Night Chancers/06.Carla's Got a Boyfriend.m4a
/music/__tmp/Baxter Dury/The Night Chancers/07.The Night Chancers.m4a
/music/__tmp/Baxter Dury/The Night Chancers/08.Hello, I'm Sorry.m4a
/music/__tmp/Baxter Dury/The Night Chancers/09.Daylight.m4a
/music/__tmp/Baxter Dury/The Night Chancers/10.Say Nothing.m4a

I checked that the path in the playlist are correct:

~ # docker compose exec -it gonic /bin/sh
/ # ls "/music/__tmp/Babylon Circus/State of Emergency/01.Monster.m4a"
/music/__tmp/Babylon Circus/State of Emergency/01.Monster.m4a
/ # ls "/music/__tmp/Babylon Circus/State of Emergency/"
01.Monster.m4a                 06.State of Emergency.m4a      11.Easy.m4a
02.Cuckoo.m4a                  07.Degeneration.m4a            12.Fire Drill.m4a
03.Dancing Girl.m4a            08.Fallin.m4a                  13.Lettre Ouverte.m4a
04.Les Oiseaux de passage.m4a  09.Tu n'ecoutes meme pas.m4a   album.nfo
05.Rio Grande.m4a              10.The Partisan.m4a            cover.jpg

I also tried to provide a very simple playlist, same result.
I'm running gonic in docker (arm64 platform).

Do you know what I could try to make it work ?
