ArgumentNullException in Designer when running in Webfarms mode
Hi there,
When we enable Webfarms mode in FR through setting the FastReportStoragePath setting we can view our reports.
But when we want to edit them we get a ArgumentNullException when the FastReport.Export.axd is setting the headers
This is the full stacktrace:
[ArgumentNullException: Waarde kan niet null zijn.
Parameternaam: value]
System.Web.HttpHeaderCollection.SetHeader(String name, String value, Boolean replace) +816
System.Web.HttpResponse.AppendHeader(String name, String value) +253
FastReport.Web.Handlers.WebExport.SendDesigner(HttpContext context, String uuid) +991
FastReport.Web.Handlers.WebExport.SendObjectResponse(HttpContext context) +181
System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +867
System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) +213
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +91
Cluster mode is ON when calling FastReport.Export.axd without parameters.
We experience these issues on the 2017.* and the newly installed 2018.2.
Nothing else is changed (we had already set webReport.Report.UseFileCache = true; but that doesn't do anything without the other setting )
Is this a known issue and if so what is the solution?
With kind regards,
Sc0tTy
