Automation rule fails to create issue due to an Assets custom field validation error

Summary

During a new issue creation within an automation rule, the Create issue event fails with the error Validation failed for Insight object (customfield_12345).

Diagnosis

This behavior has been seen with various triggers and primarily to impact the Create issue action. During the automation issue creation event, the Assets custom field is attempted to be populated using an AQL query, however, editing the field fails due to a validation error resulting in the overall event to fail.

The audit log entry returns a Some Errors status. The error seen in the automation audit logs:

Error creating issue Validation failed for Insight object (customfield_12345)

Cause

The issue occurs due to a mismatch error when multiple Assets Objects are returned on the AQL used to set the field value. When the Assets custom field has Schema filtering configured and the automation rule tries to set the value to an Object that does not match the filter, a validation error occurs.

Solution

Adding further filtering to the AQL query that the automation rule is executing resolves the issue as it filters out those Objects that would not validate against the Assets custom field.

An example may be to add filtering for objectSchema, objectSchemaId, objectType, or objectTypeId.
