The trackid's return null when spotify api is used to get track information

[Pager07]

The title is my question.
Thanks,

The Track IDs contained are internal, hashed IDs and are not Spotify IDs, which is why those IDs are not being resolved against the Spotify API.

Hello @asmitapoddar, I am having trouble with that issue as well. I would like to study recommandation systems with the help of the dataset you provided. I would also like to augment your dataset with other data coming from Spotify's API. Are the track id (base 62 URI) recoverable from the hashed track_id? If not does that mean that the dataset used in your paper is not compatible with other datasets ?
Thank you for your help.
Hugo.
