Внезапно получил исключение Spotipy, http status 403, причина: нет ⇐ Python

[Anonymous]

Я создаю систему рекомендаций Spotify, используя колбу и Spotipy. У меня есть функция, в которой система может генерировать 20 рекомендаций по песням на основе артистов, которые пользователь ввел в форму HTML. Все могло бежать неделю назад без ошибок. Однако, когда я продолжал работать над этой системой в последние несколько дней, я получал SpotifyException и не смог пройти ее. Я не внес никаких изменений в свой код с того дня, как он работал.

spotipy.exceptions.SpotifyException: http status: 403, code:-1 - https://api.spotify.com/v1/audio-features/?ids=1BxfuPKGuaTgP7aM0Bbdwr,2OzhQlSqBEmt7hmkYxfT6m,4q5YezDOIPcoLr8R81x9qy,3hUxzQpSfdDqwM3ZTFQY0K,4R2kfaDFhslZEMJqAFNpdd,1dGr1c8CrMLDpV6mPbImSI,1R0a2iXumgCiFb7HEZ7gUE,0V3wPSX9ygBnCm8psDIegu,1u8c2t2Cy7UBoG4ArRcF5g,0W0iAC1VGlB82PI6elxFYf: None, reason: None

Я получил эту ошибку в консоли:
