engine

The workflow engine for the workflow. By default, Amazon Web Services HealthOmics detects the engine automatically from your workflow definition. Provide a value if you have workflow definition files from more than one engine in your zip file, or to use WDL lenient.

WDL lenient is designed to handle workflows migrated from Cromwell. It supports customer Cromwell directives and some non-conformant logic. For details, see Implicit type conversion in WDL lenient in the Amazon Web Services HealthOmics User Guide.
