Automation for Jira rules fail, and in the atlassian-jira.log we see an error message like this:

2021-09-13 20:25:07,477-0400 automation-event-serializer:thread-1 ERROR myuser 820x1204x1 ukuha7 /secure/WorkflowUIDispatcher.jspa [c.c.jira.transform.IssueBeanTransformer] Error transforming issue with key 'PROJ-100' to automation issuebean. No serializer found for class com.atlassian.jira.issue.history.ChangeItemBean and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS) ) (through reference chain:["fields"]->java.util.HashMap["customfield_12409"]->java.util.ArrayList[0])


There are two most likely causes:

  1. The referred class belongs to a custom plugin, and it doesn't have a serializer. In this example, it's a native class in Jira: com.atlassian.jira.issue.history.ChangeItemBean
  2. The custom field in the reference chain is a scripted custom field and it's failing. In this case, it's the customfield_12409


The solutions are, respectively:

  1. Engage the plugin vendor;
  2. Fix the scripting in the custom field. To get more information about this custom field, use the REST API or check the customfield table in the database.

If that doesn't fix the issue, please engage Atlassian Support.
