ERROR getImportPlaylist()

[devjaizon]

I set up explo last week and it was working fine. But this week it didn't get my new weekly playlist.

Here are the logs:

Does your timezone match up with the container and the one listed in ListenBrainz?

You can specify a timezone in docker-compose.yaml

Also, has ListenBrainz generated you a playlist for this week?

Can you try running it again?
It seems like ListenBrainz API failed to respond, maybe it was down?

[devjaizon]

I tried again, and it says:

2025/12/19 12:21:05 INFO Starting Explo... 2025/12/19 12:21:10 ERROR failed to get weekly-exploration playlist, check if ListenBrainz has generated one this week

ListenBrainz did create my playlist, as you can check here: https://listenbrainz.org/playlist/3c4cacda-6fc0-4d67-af3f-1137f0cb3acd/

[devjaizon]

Update: changing LISTENBRAINZ_DISCOVERY to api I was able to make it work, it created "Weekly-Exploration-2025-Week51" with 25 musics.

I tried switching back to playlist and the error persists: ERROR failed to get weekly-exploration playlist, check if ListenBrainz has generated one this week

[LumePart]

I think the API endpoint is not that stable today, I also get a few errors where the server is resetting my request.
I'm leaving this open until I make a retry system for this issue. (e.g on fail retry every X minutes or X times until it can fetch the playlists)

Hi, just chiming in - unfortunately I'm having the same issue. Playlists are available in ListenBrainz, but somehow the cron job fails every week. Switching to api instead of playlist solves it (at least when I execute the command manually), but generates fewer songs, no?

[LumePart]

Hey!

Could you run this command at the same place where explo is running

wget -o output.txt https://api.listenbrainz.org/1/user/YOUR_LB_USERNAME/playlists/createdfor

(replace YOUR_LB_USERNAME with your actual ListenBrainz username)

and then cat the output.txt file to verify if you got a response in JSON

Also please note how long the request takes (approx)

If explo runs in docker, you have to first enter the container before running wget:
docker exec -it explo sh

Hi, thank you for the quick response - so I ran the command both from outside and from within Docker and it was done instantenously. The response is as follows:
