Description

I'm using:

  • HangFire.Core v1.4.6
  • Hangfire.SqlServer v1.4.6
  • Windows 10 x64
  • IIS 8.5 (not important probably but still)

Suddenly I got failed jobs containing next exception:

System.Globalization.CultureNotFoundException

Culture is not supported. Parameter name: name en-SI is an invalid culture identifier.

System.Globalization.CultureNotFoundException: Culture is not supported.
Parameter name: name
en-SI is an invalid culture identifier.
   at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride)
   at Hangfire.CaptureCultureAttribute.OnPerforming(PerformingContext filterContext)
   at Hangfire.Server.BackgroundJobPerformer.InvokePerformFilter(IServerFilter filter, PerformingContext preContext, Func`1 continuation)

Hangfire was using two servers if that makes any difference. After deleting all Hangfire tables it now works, but still don't know why this happened.

But why does CultureNotFoundException occurs? Thread is always running under valid culturename. I found next post: https://stackoverflow.com/questions/38690850/disable-preservecultureattribute-in-hangfire

Research direction
The issue is a CultureNotFoundException when Hangfire encounters the 'en SI' culture identifier. The key file is CaptureCultureAttribute.cs, specifically the OnPerforming method. Investigate how the culture is captured and consider adding validation to fall back to InvariantCulture or the system default culture when the specified culture is not supported. The StackOverflow link provided may offer additional insights. A potential fix could involve wrapping the culture creation in a try catch or using a culture factory method.
