Troubleshooting¶
Common issues and how to resolve them.
Workflow Editor Issues¶
I don't see any nodes in the palette¶
- Clear the cache:
drush cr - Check modules: Verify that
flowdrop_node_processoris enabled at Administration > Extend (/admin/modules). - Check node types: Verify node types exist at Administration > Structure > FlowDrop Node Type (
/admin/structure/flowdrop-node-type). If the list is empty, reinstall theflowdrop_node_processormodule.
I can't connect two ports¶
- Check data type compatibility: Port colors must match (or use "mixed" type ports). See Connecting Nodes for the full compatibility rules.
- Check direction: You must drag from an output port (right side) to an input port (left side). Input-to-input or output-to-output connections are not allowed.
- Check port type: Data ports connect to data ports, trigger ports connect to trigger ports. You cannot mix them.
My changes aren't saving¶
- Click Save: Changes are not auto-saved. Click the Save button in the editor toolbar.
- Check browser console: Open browser developer tools (F12) and look for JavaScript errors that may indicate a problem.
- Clear Drupal cache: Run
drush crand reload the editor page.
Execution Issues¶
My workflow isn't running¶
- Check workflow status: The workflow must be enabled (status = true). Edit the workflow and verify its status.
- Check pipelines: View recent pipelines at Administration > FlowDrop > Pipelines (
/admin/flowdrop/pipelines) to see if an execution was attempted. - Check logs: Look for errors in Drupal's log:
drush watchdog:show --type=flowdrop
A node shows "failed" status¶
- View the job details: Click on the failed job in the pipeline detail page to see the error message.
- Common causes:
- Missing required parameters (a required input port has no connection and no default value)
- External service errors (for HttpRequest or AI nodes)
- Entity not found (for EntityQuery or EntityContext nodes)
- Permission issues

Async workflows are stuck¶
If workflows executed with the asynchronous orchestrator appear stuck:
-
Process the queues manually:
drush queue:run flowdrop_runtime_pipeline_execution drush queue:run flowdrop_runtime_job_execution -
Check that cron is running: Async workflows depend on Drupal's queue system, which is processed during cron runs. Verify cron is configured and running.
-
Check queue status:
drush queue:list
Trigger Issues¶
My trigger isn't firing¶
- Check workflow is enabled: The workflow referenced by the trigger must have status = true.
- Check trigger config is enabled: Review trigger configurations at Administration > Structure > FlowDrop Trigger (
/admin/structure/flowdrop-trigger). - Verify conditions match: For entity triggers, ensure the entity type and bundle conditions match the actual entity being created/updated.
- Check trigger settings: Review global trigger settings at
/admin/flowdrop/triggers/settings. - Check logs:
drush watchdog:show --type=flowdrop_trigger
Orphan trigger configurations¶
If you see log warnings like Trigger @trigger references non-existent workflow @workflow, this means a trigger configuration points to a deleted workflow. Delete the orphan trigger at Administration > Structure > FlowDrop Trigger.
Monitoring¶
Where to find execution results¶

| What you need | Where to find it |
|---|---|
| All pipeline runs | Administration > FlowDrop > Pipelines (/admin/flowdrop/pipelines) |
| Individual job details | Click on a pipeline, then click on a specific job |
| Drupal watchdog logs | Reports > Recent log messages (/admin/reports/dblog) |
| FlowDrop-specific logs | Filter by type flowdrop in watchdog |
Checking logs via Drush¶
# All FlowDrop logs
drush watchdog:show --type=flowdrop
# Trigger-specific logs
drush watchdog:show --type=flowdrop_trigger
# Recent errors only
drush watchdog:show --severity=error

General¶
Permission denied¶
Ensure the current user has the appropriate permissions:
| Permission | What it allows |
|---|---|
administer flowdrop |
Full access to workflows, pipelines, and FlowDrop admin |
administer flowdrop triggers |
Create, edit, and delete trigger configurations |
view flowdrop triggers |
View trigger configuration list and details |
Permissions are managed at Administration > People > Permissions (/admin/people/permissions), filtering for "flowdrop".
How to clear the cache¶
drush cr
Or navigate to Administration > Configuration > Performance and click Clear all caches.
Where are the logs?¶
FlowDrop logs to Drupal's standard logging system (watchdog). View logs at:
- UI: Reports > Recent log messages (
/admin/reports/dblog) — filter by typeflowdrop - Drush:
drush watchdog:show --type=flowdrop
