get_recommendations bad request error

[NoahFHenry]

Hi,

Sorry if this is a dumb question in advance, I'm pretty new to coding in general so don't have the best understanding. I've encountered a Bad Request (400) error when trying to run the get_recommendations and add_tracks_to_playlist functions, but cannot figure out why as other functions seem to be working fine. I've run this syntax before without any issues, but seemingly get an empty vector when I run the get_recommendations argument, and an HTTP 400 error when trying to add things to a playlist. For clarity, here is the relevant part of the syntax I'm having trouble with:

`# packages
library(spotifyr)
library(lubridate)
library(knitr)
library(httpuv)

Sys.setenv(SPOTIFY_CLIENT_ID = 'MY_CLIENT_ID')
Sys.setenv(SPOTIFY_CLIENT_SECRET = 'MY_CLIENT_SECRET')
access_token <- get_spotify_access_token()

recommendations (no problems in prior use)

recommended_tracks <- get_recommendations(limit = 25, market = "GB", seed_artists = NULL,
seed_genres = "folk", seed_tracks = NULL,
target_acousticness = 0.400, target_danceability = NULL,
target_duration_ms = NULL, target_energy = 0.500,
target_instrumentalness = 0.300, target_popularity = NULL,
target_speechiness = NULL, target_tempo = NULL, target_valence = 0.400,
authorization = get_spotify_access_token(), include_seeds_in_response = FALSE)

create playlist (this bit works fine)

my_playlist <- create_playlist("MY_USERNAME", name = "Test Playlist: Folk", public = TRUE, collaborative = FALSE,
description = "Test", authorization = get_spotify_authorization_code())

add tracks to playlist (this is where the bad request error comes up)

add_tracks_to_playlist(my_playlist$id, uris = recommended_tracks $uri, authorization = get_spotify_authorization_code())`

Seeing as I've run this before without issues, I thought it might be something to do with the wrapper or the API? It doesn't make much sense to me as I don't think there is much wrong with the syntax. I'd be grateful for any help/advice!
