Hello,
Can anyone point out exactly what is happening? Our recent planned upgrade to newer versions of appian went as planned, but we started noticing missing tasks and also sudden alerts that are hard to trace where the root issue lies? Here's the stack trace, particularly unable to pinpoint exactly is the problem related to server upgrade or some missing precedent on a CDT!

There seems to be a problem executing the query rule with the UUID 483ddfd5-4250-4320-9a80-3ebbe68804ce. Is this an old application still using query rules? Try to search for this UUID in Designer and hunt down the depending processes. Then check them.
Please open a support case as an Appian upgrade should not impact existing apps.
