Other day we were getting “Unexpected” exception while opening a ‘Contact’ record.

There were no error details to check at application level.

When I verified my CRM application server’s Event viewer, there was below error log

Exception of type ‘System.Web.HttpUnhandledException’ was thrown.

at System.Web.UI.Page.HandleError(Exception e)

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Index was outside the bounds of the array.

Fix:

  • By resetting the IIS on CRM application servers solved the issue.

Reason:

  • Not sure what caused this exception, as nothing had been customized on Contact entity.
