Question / Problem:
When attempting to export large Excel files, HTTP 500 error is thrown with the following text in Viewer's log. What causes that and how can it be resolved?
ERROR Insight.App_Code.serviceHandler - https://127.0.0.1/WcfDataService/Htm.../ExportToExcel
System.Threading.ThreadAbortException: Thread was being aborted.
Answer / Solution:
This issue occurs when the service handler times out before the data service can provide a response. In v5.x, the default timeout is 90 seconds. To fix this, modify the Viewer application's web.confg file as follows:
- Backup existing copy of \Program Files\Kofax\Insight 126.96.36.199\HtmlInsightView\View\web.config
- Edit the file and note the following section:
3. Add the following entry to the existing httpRunTime line:
- Save the file
- Perform an IIS reset or restart the Insight 5.4 Application Pool
