The WorkflowExecutionStepError exception is raised when a workflow step encounters an execution error.
The WorkflowExecutionStepError exception is raised if the workflow step cannot be executed. For example, trying to execute an unsupported step such as DefineAOI, EditExtendedProperties, LaunchArcMap, LaunchGP, OpenMap, and SelectDataWorkspace will raise the error.
The WorkflowExecutionStepError exception is used below to handle any errors that result from trying to execute a step in the workflow.
