NullReferenceException at GetClientCompression(HttpContextBase context)

[deekoulos]

Hi @Shazwazza

using Umbraco 8.18.4 and ClientDependency 1.9.10

we are getting new Exceptions since upgrading to 8.18.4 with the following information:

Message:
Unhandled Exception! Url: /DependencyHandler.axd?s=L1NjcmlwdHMvY29tbW9uX3NjcmlwdHMuanM7L1NjcmlwdHMvYXV0b2NvbXBsZXRlL2F1dG9jb21wbGV0ZVdpdGhvdXREZXNjcmlwdGlvbi5qczsvU2NyaXB0cy9mdW5jdGlvbnMuanM7&t=Javascript&cdv=1849729564

Type:
System.NullReferenceException

Exception Message:
Object reference not set to an instance of an object.

StackTrace:
at ClientDependency.Core.HttpContextBaseExtensions.GetClientCompression(HttpContextBase context) in C:\Users\Shannon\Documents\_Projects\ClientDependency\ClientDependency\src\ClientDependency.Core\HttpContextBaseExtensions.cs:line 107 at ClientDependency.Core.CompositeFiles.CompositeDependencyHandler.ProcessRequestInternal(HttpContextBase context, String fileset, ClientDependencyType type, Int32 version, Byte[] outputBytes, OutputCachedPage page, Boolean& success) in C:\Users\Shannon\Documents\_Projects\ClientDependency\ClientDependency\src\ClientDependency.Core\CompositeFiles\CompositeDependencyHandler.cs:line 168 at ClientDependency.Core.CompositeFiles.CompositeDependencyHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext context) in C:\Users\Shannon\Documents\_Projects\ClientDependency\ClientDependency\src\ClientDependency.Core\CompositeFiles\CompositeDependencyHandler.cs:line 135 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

We can't reproduce it on demand but this exceptions comes up once or twice a day.

We also still get the following exception since using CD:

at ClientDependency.Core.CompositeFiles.CompositeDependencyHandler.ValidateRequest(HttpContext context, String& fileKey, ClientDependencyType& type, Int32& version) in C:\Users\Shannon\Documents\_Projects\ClientDependency\ClientDependency\src\ClientDependency.Core\CompositeFiles\CompositeDependencyHandler.cs:line 37 at ClientDependency.Core.CompositeFiles.CompositeDependencyHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext context) in C:\Users\Shannon\Documents\_Projects\ClientDependency\ClientDependency\src\ClientDependency.Core\CompositeFiles\CompositeDependencyHandler.cs:line 94 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Any ideas?
