Hi,
I had a javascript button that performed some validation and update via APEX in classic and when transitioning to Lightning I create a Lightning quick action (aura component) to replace it. A button opens the action on the Opportunity detail page in a Lightning console. The component opens fine but when trying to Confirm I got an error message "Uncaught Error in $A.getCallback() [Cannot read property 'setParams' of undefined].Callback failed:apex...".
Aura component:

<aura:component implements="flexipage:availableForAllPageTypes,force:lightningQuickActionWithoutHeader,force:hasRecordId" access="global" controller="ConvertAPEX">             

    <aura:attribute name="recordId" type="String" /> 
    <aura:attribute name="opportunity" type="Opportunity"  /> 

    <div class="slds-hide">
    <lightning:recordEditForm aura:id="editform"
                                  recordId="{!v.recordId}"
                                  objectApiName="Opportunity">        
           <lightning:outputField fieldName="Account_Status__c" aura:id="status"/> 
           <lightning:outputField fieldName="IsClosed_text__c" aura:id="closed"/>  
    </lightning:recordEditForm>    
    </div>

    <div class="slds-modal__header">             
       <h2 class="slds-text-heading_medium slds-hyphenate">Convert</h2>        
    </div>

    <div class="slds-modal__content slds-p-around_medium" id="modal-content-id-1">
         <p>You are about to convert this record.</p>
            <br/>
         <p>Are you sure you want to continue?</p>      
    </div>

    <div class="slds-modal__footer">
        <lightning:button class="slds-button_brand" onclick="{!c.convertRegistration}" label="Confirm" />
        <lightning:button class="slds-button_neutral" onclick="{!c.cancel}" label="Cancel"/>

        action.setParams({
