After clicking to Try it out button of PUT /v1/order-candidates method, Swagger auto-fills the body. Clicking on Execute executes the request as expected. When the optional (i.e., not required) pickupLocation entry is removed from the body, clicking on Execute doesn't respond.
Expected behavior
When the optional (i.e., not required) pickupLocation entry is removed from the body, clicking on Execute should execute the request.
