You're right, that stacktrace really isn't helpful in troubleshooting this issue. To be honest, I only recognized it because I handled the support ticket that resulted in that section being added to the upgrade guide. The chart was a bit more complex as it had been in use on 7.9 but it took a while to isolate the problem to the qualified value being stored in the SFC Parameter. There is [this](https://forum.inductiveautomation.com/t/uncaught-exception-executing-batch-contex/46555) other forum post that has the same stacktrace where it's mentioned that serializing the quality code in the Qualified Value object is an issue. I believe we made a change to dataset tags to prevent attempting to serialize quality codes so I'll see if there may be a similar change we can make to the SFC parameters. Or at the very least, see if we can add logging that would point you in the right direction. --- _[View the full topic](https://forum.inductiveautomation.com/t/bug-7073-sfc-monitoring-just-shows-java-lang-reflect-undeclaredthrowableexception-when-storing-a-qualified-value-in-a-chart-parameter/68705)._
