[CRASH] - Tempus crashes on startup

[srett]

Description

Installed Tempus a few days ago (was on Tempo before), today I can't launch it anymore. Barely used it, played some songs from existing playlists. Server is LMS.

Steps to Reproduce

In case the logcat output below doesn't immediately give a clue as to what's wrong, I can investigate this, but really as mentioned above I just played some existing playlists yesterday, closed the app, then today it won't launch...

Environment

• Android device: Xiaomi Redmi Note 4/4X (mido)
• Android OS version: LineageOS 22 (Android 15)
• App version: 4.12.0 (just updated from 4.11.0, issue persists)
• App variant: degoogled

What server back end are you using?
this seems to be where it dies.

Any more details you can give me on that particular track (meta data) would be helpful to narrow down the issue.

I'm using lightweight music server.

lms ships the tool lms-metadata which you can call on a file and it dumps all the metadata it would extract from the file:

Which Subsonic call would I have to make to debug this further? Interestingly, I don't see a single call for tr-7108 from Tempus in the access logs.
In any case, I just manually ran this, in case that helps:

would it be possible to do a full wipe and a clean install while i dig further on the metadata ?
It's trying to create an instant mix however, Im not sure how you are getting there on start up as that generally requires a button press. But hopefully that will get you going. I suspect something else corrupted the db.

Question for you, what do you use to tag your music? Funnily enough, that album is in my queue/rotation at the moment and I also use lms. When I look at the response and the error message, i find that your copy is missing a genre and I believe the code is looking for that field to not be empty. So it is probably a bug that I will need a way to figure out how to test. Although I am confused on how it is keeping the app from starting unless all your tracks have a similar missing genre tagging issue.

@FrankyHolly any logs, perhaps server logs even?

[eddyizm]

Thanks @FrankyHolly - seems to be the same issue as OP. Do you happen to have server logs , eg is it getting to the server at all and triggering api calls? I am not able to replicate this on either variant on my physical device or emulator. I also tested ampache, navidrome and lms. I'm kinda guessing it is a null field but also guessing which one it is.

Would it be possible to get a test account on your server? I am assuming you are able to consistently crash?

[FrankyHolly]

Crashes are consistent. A test account is unfortunately not an option but I will dig into the server logs this afternoon to see if I can find anything. Prior to ver 4.12.0, for many months, the app ran without issues.

[eddyizm]

yeah, i'm looking at the changes in that version and there were things regarding the radio stations which i have no way to test myself. That is the biggest suspect since it's hinting at the mapping util, the layout changing, i assume, would give a different error.

Is your server serving up podcasts and radio stations?

[FrankyHolly]

Positive on the radio stations, negative on the podcasts

[srett]

Sorry, probably was a bit too brief in my original post, but I ran into this issue on 4.11.0, and then updated to 4.12.0, with no change in behavior. So looking at the changes between 4.11 and 4.12 might not reveal anything.
I neither have podcasts nor radios set up.

would it be possible to do a full wipe and a clean install while i dig further on the metadata ?

Sure, I just left it in that state in case I could do some further steps that help debugging.
I just wiped all data from Tempus and started over, and briefly tried a few things to trigger this, mainly by playing and fiddling around with the song mentioned in my crash reports, as well as opening the according playlist, the album, etc., restarting the app in between. No crash so far.

Question for you, what do you use to tag your music?

I'm currently using picard 2.13.3 (ships with Debian 13).
