Condition

ArgumentException

elementsToMirror cannot be mirrored. -or- The given element id set is empty. -or- One or more elements in elementsToMirror do not exist in the document. -or- Some of the elements cannot be copied, because they belong to different views. -or- The input set of elements contains Sketch members along with other elements or there is no active Sketch edit mode.
