vue.runtime.esm.js:619 [Vue warn]: Error in v-on handler: "TypeError: Cannot read properties of undefined (reading 'refresh')" found in

It seems that there is an error in the `v-on` handler of your Vue component. The error message indicates that there is an attempt to read the property 'refresh' from an undefined object.

To troubleshoot this issue, you can start by checking the code within the `v-on` handler and ensure that the object is properly defined before accessing its properties. Make sure that the object you are trying to access the 'refresh' property from is not null or undefined.

Here's an example of how you can handle this situation:

// Assuming you have a method called 'handleRefresh' in your component
methods: {
  handleRefresh() {
    if (this.object && this.object.refresh) { // Check if object and its 'refresh' property are defined
      // Perform the necessary actions
    }
  }
}

By adding a null check or undefined check before accessing the property, you can prevent this error from occurring.
