Error in v-on handler TypeError moment__WEBPACK_IMPORTED_MODULE_6___defaultformart is not a functionfound in--- ElButton at packagesbuttonsrcbuttonvue ElDialog at packagesdialogsrccomponentvue

The error is caused by calling the "format" method on an object that is not a moment object or does not have the "format" method defined. The code may be passing an incorrect argument to the moment function or may be using the wrong syntax to call the "format" method. The code should be reviewed to ensure that the correct argument is passed to the moment function and that the "format" method is called correctly.
