Which of the following may indicate that your process model has errors or issues?

A publish error in a dialog or below the process model indicates that there are errors in the configuration or design of your process model. When you attempt to publish a process model in Appian, it goes through a validation check. If there are any issues such as incorrect configurations, missing required fields, or syntax errors, the system generates a publish error. This serves as a clear indication that the process model cannot be executed as intended and requires troubleshooting to resolve the issues present.

In contrast, the other options represent states that do not necessarily indicate problems. A green outline around a node typically signifies that it is properly configured and does not have issues. The highlight in blue generally indicates that the process or node is currently selected and does not relate to any errors. Data not appearing in the Variables tab might suggest an issue with the data flow but isn’t a direct error related to the model itself. Therefore, the presence of a publish error clearly signifies something is wrong with the process model that needs rectification.
