Symptoms

When moving an issue in the JIRA Agile Rapid Board, an error occurs and displays:

Cause

The error is caused by a third-party plugin that is not compatible with the current version of JIRA.

 This was replicated with the Database Custom Field v.2.1.2 plugin.  

Workaround

As we do not have a comprehensive list of all plugins that can cause this problem, the plugin will need to be identified through isolation testing. This can be done with the following steps.

1. First, attempt to upgrade all your plugins and then see if the problem is still persistent - it may be a plugin developer has corrected the incompatibility.
2. If the problem is still present, disable all plugins through the UPM except for JIRA Agile, as in Disabling a JIRA Plugin.
3. Enable each plugin one-by-one, whilst monitoring the logs for the error message and also checking JIRA Agile for any browser errors that may have been present.
4. When you find the problematic plugin, please keep it disabled and forward the problem to its vendor, whose details can be found on the Atlassian Marketplace.
