TypeError: Cannot read property 'ownerDocument' of null {stack: (...), message: "Cannot read property 'ownerDocument' of null"}

Encountered the error in the followin line after upgrading the dojo code.Anyone knows how I can fix it, or should I report it as a bug?

domConstruct.place(legPic, curLayer.id + '_chkBox_' + curLegLyr.layerId, "after");
