Error retrieving an Apple Music playlist

[JustTooKrul]

I was using freyr in conjunction with an Apple Music account and made one playlist with my entire library on it. This playlist consists of 1,077 items (the "Tracks" number reported). However, at the "Inquiring tracks" step the program gives an error:

[•] Inquiring tracks...(failed: [expecting an array or an iterable object but got [object Null]])
[i] An error occurred while processing the query (Failed to collect playlist tracks)

On the off chance that this was based on the time to retrieve data from Apple Music, I ran it again with the timeout set to 100,000ms (vs. the default of 10,000), but the same error occurred.

Hi there, can you try a smaller playlist? Create one much like yours with a smaller set of songs, and see that.

It could be that the playlist is private so freyr cannot access it, unsure.

What's the total runtime?

[JustTooKrul]

Very odd, but I literally just retried it a number of times and eventually (I would say on the 10th try or so, and with the extra long time out) it just "worked" ... However, it stopped partway through with a message "Program was killed." ... But, I re-tried it a number of times again and eventually it worked again and skipped what was already there and completed.

I kept retrying because it was a new list, so I thought maybe it wouldn't be accessible yet and might take some time to propagate, but then it wouldn't have stopped working after it worked that first time.

I had also downloaded 3-4 other lists, and it worked for those (largest was ~600 or so tracks).

Interesting, there's a chance the kernel is killing the process for excessive memory use

Can you highlight which platform you're running this on, and the resources available

Perhaps we can track how much memory was in use before the process dies

[JustTooKrul]

It's a VM, through proxmox, that I have setup to use 4 CPUs and 32GB of memory with a 100GB disk... Hard to know how much this was taking up, since I have a few things running on it (this machine runs Docker, and has a number of images spun up). What else would be helpful to know or what outputs can I run to show you what you need?

[miraclx]

Can you time the runtime with verbose logs?

There's different variants of the time command so it's tricky to say which command you should use

But if which time says it's a shell built in, you need to install the binary

Thereafter, test it with either -v, -l or -p

What were gunning for here is a multiline report of multiple data points including memory (resident set size)

So, funny story, it worked when I ran it....

Here is the output (including the summary from freyr):

I then tried it again, and it failed....

Thanks for the logs, will investigate
