Typecheck failures

One failure was encountered and fixed before writing the sample file:

Task 2 (372-workflow-input-validator): The local type annotation { default?: string } conflicted with exactOptionalPropertyTypes: true when assigning string | undefined. Fixed by widening to { default?: string | undefined }.
