4.1 -> 4.2 Seeing "500" errors on datatables grid pages

4 months ago
We're seeing this after upgrading a site from 4.1 to 4.2.


These pages throw a 500 "Internal Server Error".

Any ideas on how to track this down?

Try clearing your browser cache and see if that works.

If you have the source we would suggest you debug the code. Start at


\LogController.cs > List()
\OrderController.cs > OrderList(OrderSearchModel searchModel)

This could also be caused by a plugin you may have installed.

You can write logs to see exactly where the error is, then find the cause to fix. Open file web.config Set stdoutLogEnabled="true"

<aspNetCore requestTimeout="23:00:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" forwardWindowsAuthToken="false" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" startupTimeLimit="3600" />
