Field Required Validator Issues after migration to cloud

While migrating the JSU validator to the cloud environment, you might see these messages:

2022-02-01 13:50:03.532 ERROR YOURPROJECTNAME project-export The workflow: [YOURWorkflow] transition: [YOURTRANSITION] is missing config [contextHandling] for workflow rule validator [FieldsRequiredValidator]. Double-check the workflow rule for missing config values or references.

This error will occur because the field-required validators were created with an older JSU version before version 1.4.10 that did not use these fields. Now, these fields are mandatory and necessary to achieve the migration of these validators.

How to confirm the issue:

Export your workflow and check the XML file; the field ContextHandling and other fields are missing from the validator.
From one of the validators that are causing this issue:

      <validators>
        <validator name="" type="class">
          <arg name="hidFieldsList">resolution@@</arg>
          <arg name="class.name">com.googlecode.jsu.workflow.validator.FieldsRequiredValidator</arg>
        </validator>
      </validators>

From a healthy and working validator after migration:

<validators>
  <validator name="" type="class">
    <arg name="contextHandling"/>
    <arg name="hidFieldsList">attachment@@comment@@</arg>
    <arg name="jsuWorkflowParamsVersion-textValue">2.28.1</arg>
    <arg name="class.name">com.googlecode.jsu.workflow.validator.FieldsRequiredValidator</arg>
    <arg name="customErrorMessage-textValue">Adding these fields is Mandatory! Attachments & Comments.</arg>
    <arg name="uuid">05108e3a-06e8-4598-bbf2-ffd22596c1e5</arg>
  </validator>
</validator>
