LWC - Run Event on Child when Datable Row Selected on Parent

Question

I am trying to run an Event on my Child Component when the Datable row is selected on my Parent Component.
I am receiving the error below

Here is the Event code from my Child Component

handleCancel(event){
    const inputFields = this.template.querySelectorAll( 'lightning-input-field' );
    if ( inputFields ) {
        inputFields.forEach( field => {
        field.reset();
        this.showSaveButton = false;
        } );   
    }
}

Here is the Event code from my Parent Component

handleRowSelection(event){
        var selectedRows=event.detail.selectedRows;
        this.werRecordId = selectedRows[0].Id;
        this.template.querySelector('c-work-experience-record-page').handleCancel();
        this.werSelectedRow=true;
    }

Error

[NoErrorObjectAvailable] Script error.

Answer 1

I figured out the issue.... I forgot to add an @api decorator on the Event in my Child Component to expose it to the Parent.

@api
handleCancel(event){
    const inputFields = this.template.querySelectorAll( 'lightning-input-field' );
    if ( inputFields ) {
        inputFields.forEach( field => {
        field.reset();
        this.showSaveButton = false;
        } );   
    }
}
