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 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.
