I am trying to open a modal once clicking on a button which is in the parent component. For that I have used aura:method in the child component and calling that child component in the parent component with a unique aura:id. The code is as below.

Parent.component

<aura:component>
<c:ChildCmp aura:id="showViewDetailsModal" />
                 <lightning:button variant="brand" label="Open Modal" title="Open Modal" onclick="{!c.openViewDetailsModal}" />
</aura:component>

Parent.controller

({
    openViewDetailsModal : function(component, event, helper) {
         component.find('showViewDetailsModal').showViewDetailsMethod(true);
    }
})

Child.component

<aura:component>

    <aura:attribute name="isOpen" type="Boolean" default="false" access="public" />
   
    <aura:method name="showViewDetailsMethod" action="{! c.openViewDetailsModal }" access="public">
        <aura:attribute name="openViewDetails" type="Boolean" default="false" />
    </aura:method>

    <aura:if isTrue="{!v.isOpen}">
        <div role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true"
            aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">
            <div class="slds-modal__container">
                <div class="slds-modal__header">
                    <lightning:buttonIcon iconName="utility:close" onclick="{! c.closeModal }" alternativeText="close"
                        variant="bare-inverse" class="slds-modal__close" />
                    <h2 id="modal-heading-01" class="slds-text-heading_medium slds-hyphenate">
                        Program Detail</h2>
                </div>
            </div>
        </div>
    </aura:if>
</aura:component>

Child.Controller

({
    openViewDetailsModal : function(component, event, helper) {
        var params = event.getParam( 'arguments' ) || event.getParam();
        component.set('v.isOpen',params.openViewDetails);
    },
        
    closeModal : function(component, event, helper) {
        component.set('v.isOpen',false);
    },
})

The error is as below.

Action failed: c:ChildCmp$controller$openViewDetailsModal [component.find(...).showViewDetailsMethod is not a function] Failing descriptor: {c:SAPProgramSearchGetDataComponent$controller$openViewDetailsModal}

Can someone help me to solve this isuue?

I tried your code and it works well. Few pointers when working with Lightning.

  1. Check if your code is deployed properly.
  2. Always use Ctrl+Shift+R to reload the browser when testing an aura component.
  3. Try clearing your browser cache and cookies and then reload the browser again.

Just FYI : Avoid using var, try using const or let.

NOTE

I just added an extra implements="flexipage:availableForAllPageTypes" in your parent component to just make the component available on the flexipage, so as to test this. That shouldn't make any difference though.

enter image description here

you should replace this with <c:Child ....> only according to your child component name.
