My guess would be something like you've added a property to the manifest file but not set it's value, or you've said you CSS files but set an empty array.
Without seeing your files it's hard to diagnose but it's not an error I've ever come across before.
ManifestParser Exception
Hi,
We are getting the below exception repeated heavily on our environment
System.NullReferenceException: at Umbraco.Core.Manifest.ManifestParser.ParseManifest (Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null: D:\a\1\s\src\Umbraco.Core\Manifest\ManifestParser.cs:167) at Umbraco.Core.Manifest.ManifestParser.GetManifests (Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null: D:\a\1\s\src\Umbraco.Core\Manifest\ManifestParser.cs:82)
Any clue how to get rid of it?
Hi Kareem,
Have you got any custom PackageManifest files? If so, what do they look like? My guess is that there is an issue in one of them, but I can't be sure.
Thanks
Nik
Hi Nik,
Any clue about what kind of issue that might be there? Can it be wrong path for a dependency for instance or something else?
Regards, Kareem

To help in your diagnosis, I believe that this is the code that is failing:
https://github.com/umbraco/Umbraco-CMS/blob/b8db430615d76521a4394a23f9928dc7c12f87bd/src/Umbraco.Core/Manifest/ManifestParser.cs#L169
Looking at that, I suspect you have a property editor defined incorrectly in a package manifest file.
is working on a reply...
