at com.googlecode.jsu.workflow.validator.FieldsRequiredValidator.validate(FieldsRequiredValidator.java:123)Solution
Some workflow validator is configured for the Create Issue transition on the target workflow e.g. Fields Required Validator from JIRA Suites Utilities Plugin.
Workaround
Edit the relevant workflow on the target instance before import, and remove the validators (i.e. if the requirements imposed by this validator are no longer actually required; or if it is more important to import the data as-is than to enforce constraints on the data).
Resolution
Ensure that all requirements imposed by the Workflow Validators on target instance are met. e.g. If you have a Fields Required validator on Create Issue transition of target workflow that makes Assignee field required, then you should make sure that all the matching issues being imported (for the relevant project and issue type) have assignee field set.
