Question

In the interface, the button uses a!startProcess. Although the process instance is created and completes successfully, the a!startProcess function still routes execution to the onError block.

When using a!startProcess within the interface button, the process instance is successfully created and completes as expected. However, despite the successful execution, the a!startProcess function moves to the onError block, resulting in unintended error.

However, despite the successful execution

How do you know this?

As per the documentation, onError is triggered when the process could not get started. Did you check process model security, process parameters, passed data and data types?
