Environment

Release: Any

Cause

This issue is not caused by the Clarity product, it's caused by a customization (third party product):

• com.compuware.apm.agent.introspection
• Dynatrace by Compuware
• This is not a Clarity code class.

Resolution

• We suggest to work with Dynatrace support to resolve this
• We have been told that Dynatrace  RUM (Real User Monitoring) may have to be disabled for the duration of the upgrade
