Spotify /recommendations endpoint returning an empty array for tracks

[Dryd3n]

My Question or Issue:

When making a call to the /reccomendations endpoint, I get a seemingly regular response to the API call, except the tracks array is empty. 

Call code:

Response:
{
"tracks" : [ ],
"seeds" : [ {
"initialPoolSize" : 0,
"afterFilteringSize" : 0,
"afterRelinkingSize" : 0,
"id" : "meme rap",
"type" : "GENRE",
"href" : null
}, {
"initialPoolSize" : 0,
"afterFilteringSize" : 0,
"afterRelinkingSize" : 0,
"id" : "irish drill",
"type" : "GENRE",
"href" : null
}, {
"initialPoolSize" : 0,
"afterFilteringSize" : 0,
"afterRelinkingSize" : 0,
"id" : "uk hip hop",
"type" : "GENRE",
"href" : null
}, {
"initialPoolSize" : 0,
"afterFilteringSize" : 0,
"afterRelinkingSize" : 0,
"id" : "lo-fi rap",
"type" : "GENRE",
"href" : null
}, {
"initialPoolSize" : 0,
"afterFilteringSize" : 0,
"afterRelinkingSize" : 0,
"id" : "uk drill",
"type" : "GENRE",
"href" : null
} ]
}

as you can see the api returns the seeds but the track array is empty...

Hey there, help's here!

Hmm, it seems that the genre seeds you've provided aren't valid (meme rap, irish drill, lo-fi rap, uk drill). You can get all available genre seeds with this endpoint: https://developer.spotify.com/documentation/web-api/reference/#/operations/get-recommendation-genres.

Could you try using a genre seed from that list (e.g. 'techno') and see if the same thing happens?

Keep me posted! 🙂

Have a great day,

Thanks  Hubo, you where correct. I assumed those genre seeds to be valid because I pulled them from the artists endpoint so I just assumed that they would have been valid genre seeds but I guess not. Thanks anyway
