Our API depends on null's being allowed as part of the request:

const updateWidgetRequest: UpdateWidgetRequest = {
  name: 'Sproket',
  size: 5,
  inspectionDetails: null,
};

This is different than sending undefined for inspectionDetails. Our API treats undefined on patch as no change, but null as a means to clear the value.

While the swagger file defines the type as nullable, the generated code only allows InspectionDetails | undefined

We've tried to hack a value by doing:

inspectionDetails: <InspectionDetails>(<unknown>null)

This is awful and still doesn't work. This call to writeObjectValue strips it.
