Caused by: java.lang.IncompatibleClassChangeError: Found interface com.atlassian.jira.plugin.customfield.CustomFieldTypeModuleDescriptor, but class was expected
at de.phil.jira.plugin.OverdueField.getHoursToAddToDuedateParam(OverdueField.java:38)
at de.phil.jira.plugin.OverdueField.getValueFromIssue(OverdueField.java:63)
Cause
The error is caused by a third-party plugin installed on the instance that is not compatible with the JIRA version. In order to find out the name of the plugin, look closely on the 'Caused by' section of the stack trace. In this case, it is the 'Overdue' plugin.
Resolution
Disable the incompatible plugin through the UPM, as in our Managing JIRA's Plugins documentation so the JIRA instance will be usable.
Identify the plugin developer on the Atlassian Marketplace and contact them directly with the error.
