Playbook's automations do not list referenced activity and show 'asset not found' error Issue ProblemWhen viewing the Automation tab in a playbook step that points to a subflow or action, the referenced activity is not listed, and attempting to load it results in an 'asset not found' error. Reproducing the issue involves navigating to Workflow Studio, opening a playbook, selecting a stage and step, and observing the error when accessing the Automation tab. Additional errors include 'Corrupted flow' and validation errors related to undefined fields in PA Designer. Symptoms Click on the arrow to open the flow/ subflow. Flow/subflow shows an "Asset not found" error. Release Australia Patch 5 Cause 1. Corruption or misconfiguration of playbook-related plugins (PA Designer, Unified Developer Core) caused referenced activities to fail resolution.2. Cached data in the instance prevented updated or corrected configurations from taking effect.3. Missing or incorrect permissions for users attempting to view or configure playbook activities. Resolution 1. Repair the PA Designer and Unified Developer Core plugins to address potential corruption or configuration issues.2. Clear the instance cache to ensure outdated data is removed and resolved.3. Verify that the referenced subflow or action is published and not deleted, as only published assets can be linked in playbook activity definitions.4. If new input fields were added to a subflow, update the activity definition's input visibility to 'Show as additional property' in the sys_pd_activity record.5. Confirm that the user has the required roles (admin, playbook.admin, or pd_content_author) to view and configure playbook activities and automations.
