Error in v-on handler: "typeerror: cannot read property 'resetfields' of undefined"

vue The project with elm Frame write form
When adding, the data should be cleared this.$refs['form'].resetFields();
But when the page loads in, it hasn't been rendered yet dom Elements
Therefore, clicking Add directly will report an error ：

Error in v-on handler: "TypeError: Cannot read properties of undefined (reading 'resetFields')"

Solution ：
1、 Add judgment 

if(this.$refs['form'] !== undefined) {
    
  this.$refs['form'].resetFields();
}

2、 Delay callback 

this.$nextTick(() => {
    
	this.$refs['form'].resetFields();
})
