The StartWorkflowExecution API action was called without the required
parameters set.
Some workflow execution parameters, such as the decision taskList, must be
set to start the execution. However, these parameters might have been set as defaults when the
workflow type was registered. In this case, you can omit these parameters from the
StartWorkflowExecution call and Amazon SWF uses the values defined in the workflow
type.
If these parameters aren't set and no default parameters were defined in the workflow
type, this error is displayed.
