Resolve invalid steps, unreachable paths, and common workflow validation errors.
DocQ validates workflows before they can be saved and activated. A workflow must meet several requirements to be considered valid. This page covers the most common validation errors and how to resolve them.
A workflow can only be saved when all of the following conditions are met:
If any of these conditions are not met, DocQ will prevent the workflow from being saved and highlight the issues on the canvas.
Invalid steps are indicated by a red border on the canvas. A step becomes invalid when it is missing required configuration.

All steps except the End step must have a default next step configured. Specifically:
Info
Even when conditions cover every possible scenario, the default next step is still required as a fallback. See Conditions & Routing for details.
Some step types require specific configuration fields to be completed. When a required field is empty, the step is highlighted with a red border in the step settings panel. Common examples include:
Open the step settings and fill in all highlighted fields to resolve the error.
Every step on the canvas must be linked to the Start step through at least one path. A step is considered unreachable if there is no chain of connections leading from Start to that step.
This validation ensures that no orphaned steps exist in the workflow. Multiple paths to the same step are allowed — the requirement is simply that at least one valid path exists.
To resolve this issue:
Warning
Unreachable steps can occur when you delete a connection between two steps or remove an intermediate step. Always verify the workflow's connectivity after making structural changes.
A workflow can only be deleted if none of the following are currently using it:
To delete a workflow:
If the workflow is in use, DocQ will display a message indicating what is referencing it. You must remove those references before the workflow can be deleted.
