Not able to reproduce so far, but I'll leave open while we await other reports.

Any particular section or app profile trigger this for you?

[corsairius]

Just entering the Apps section throws this error.

[kesselb]

Hi,

please apply the following patch to your installation. Then try opening the apps section again and then check your logfile for "array given to DependencyAnalyzer.getValue" and share the complete logline with us.

Thanks 👍

Somehow, the min-version definition for a database in info.xml seems to trigger that error.

To loop over all files and find the min-version definitions:
grep -i -r "<database min-version=" .

I think it could be the sensorloggers app:
https://github.com/search?q=%3Cdatabase+min-version%3D%225.7&type=code

The definition itself looks correct. I'm unsure why it fails here.
Maybe because it's only one database definition.

Seems like this block is missing to make it work.
However, comparing the min-version for database is not implemented anyway 🙈

@corsairius It should work again if you remove the sensorloggers app (if possible with occ or by deleting the folder).

[corsairius]

Removed the sensorloggers from the disabled app list, as well as the others hanging around. Appears corrected. Thanks!
