GET (...)/owncloud/index.php/apps/music/api/collection 500 (Internal Server Error)

[GerardGarcia]

Music app just stopped working. Chrome developer tools says:

GET (...)/owncloud/index.php/apps/music/api/collection 500 (Internal Server Error)

If I access directly to the URL /owncloud/index.php/apps/music/api/collection it seems to work (it just shows one file but I don't know if this is normal)

Using owncloud 7.0.2 and latest music from git repo.

[GerardGarcia]

Steps to reproduce

Fresh installation with latest music app from master branch.
I don't know if it is relevant but I symlink my music folder to the owncloud music folder.
Update library.
Play some music.
Come back later, music app frozen at the loading page. Chrome developer tools show that the error comes from GET (...)/owncloud/index.php/apps/music/api/collection 500 (Internal Server Error).

Expected behaviour

I should be able to access my music files.

Actual behaviour

I can't access my music files.

If I checkout to the latest tag v0.3.4 the error still persists. But It works with version tagged v0.3.3.

[GerardGarcia]

I have tracked down the error to:

if I checkout to this commit and onwards it stops working.

[paulijar]

I believe the significant part of the commit 49b166d mentioned above are the changes to method Track.toCollection. After those changes, loading the collection.json fails with 500 if the collection contains even single dangling track reference to a file which is no longer available for the user. Such references could occur e.g. in scenario described in #567. The toCollection method was changed again as part of #564 and now the dangling references no longer break the loading of collection.json. Hence, this issue should be fixed for the latest release and can be closed.
