Rest API widget GET endpoint returns 200 but widget PATCH returns 404 with same dashID and widgetID

When calling the widget GET endpoint with a valid dashboardId and widgetId, I get a 200 response with expected widget information.  But when calling the widget PATCH endpoint with the same dashboardId and widgetId and a valid request body, I get a 404 with a response that says the widget was not found under the dashboard.  I attached a screen shot to help clarify.  How does this make sense when the GET returns a 200?  What could I be doing wrong?
