Error on "Build a Lightning Component to Override a Standard Action Use Lighting Data Service" Trailhead

Hi there

I'm getting an error message on this Trailhead Module and I don't know what I'm doing wrong.  I have been trying for a couple of days and can't work out what my error is.

Here is my Developer Console code:

​

PROPERTY DIALOG COMPONENT:

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId" access="global" >

    <aura:attribute name="picklistValues" type="Object" />

    <aura:attribute name="propertyRecord" type="Property__c" />

<force:recordData aura:id="forceRecord"

                recordId="{!v.recordId}"

                targetFields="{!v.propertyRecord}"

                fields="Id,Name,Beds__c,Baths__c,Price__c,Status__c"

                mode="EDIT" />

    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

<c:PickListValues sObjectName="Property__c" fieldName="Status__c" picklistValues="{!v.picklistValues}" />

    <lightning:input aura:id="propName" name="propName" label="Property Name" required="true" />

<lightning:input aura:id="propBeds" name="propBeds" label="Beds" />

<lightning:input aura:id="propBaths" name="propBaths" label="Baths" />

<lightning:input aura:id="propPrice" name="propPrice" label="Price" />

<lightning:select aura:id="propStatus" name="propStatus" label="Status">

        <aura:iteration items="{!v.picklistValues}" var="item">

    <option value="{!item}">{!item}</option>

</aura:iteration>

</lightning:select>

<lightning:button variant="neutral" label="Cancel" />

<lightning:button variant="brand" label="Submit" onclick="{!c.saveRecord}"/>

</aura:component>

PICKLIST COMPONENT:

<aura:component >

    <aura:attribute name="sObjectName" type="String" />

<aura:attribute name="fieldName" type="String" />

<aura:attribute name="picklistValues" type="Object" />

    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

</aura:component>

PICKLIST CONTROLLER:

public class PickListController {

@AuraEnabled        

public static List<String> getPickListValuesIntoList(String objectType, String selectedField){

    List<String> pickListValuesList = new List<String>();

    Schema.SObjectType convertToObj = Schema.getGlobalDescribe().get(objectType);

    Schema.DescribeSObjectResult res = convertToObj.getDescribe();

    Schema.DescribeFieldResult fieldResult = res.fields.getMap().get(selectedField).getDescribe();

    List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();

    for( Schema.PicklistEntry pickListVal : ple){

        pickListValuesList.add(pickListVal.getLabel());

    }     

    return pickListValuesList;

}}

PICKLIST VALUES CONTROLLER:

({

    doInit : function(component) {

        var action = component.get("c.getPickListValuesIntoList");

        action.setParams({

            objectType: component.get("v.sObjectName"),

            selectedField: component.get("v.fieldName")

        });

        action.setCallback(this, function(response) {

            var list = response.getReturnValue();

            component.set("v.picklistValues", list);

        })

        $A.enqueueAction(action);

    }

})

PROPERTY DIALOG CONTROLLER:

({

    doInit : function(component, event, helper) {

        

    component.find("forceRecord").getNewRecord(

        "Property__c",

        null,

        false,

        $A.getCallback(function() {

            var rec = component.get("v.propertyRecord");

            var error = component.get("v.recordError");

            if (error || (rec === null)) {

                console.log("Error initializing record template: " + error);

                return;

            }

        })

    );},

    saveRecord : function(component, event, helper) {

var propBeds = parseInt(component.find('propBeds').get("v.value"), 10);

var propBaths = parseInt(component.find('propBaths').get("v.value"), 10);

var propPrice = parseInt(component.find('propPrice').get("v.value"), 10);

component.set("v.propertyRecord.Name", component.find('propName').get("v.value"));    

component.set("v.propertyRecord.Beds__c", propBeds);

component.set("v.propertyRecord.Baths__c", propBaths);

component.set("v.propertyRecord.Price__c", propPrice);

component.set("v.propertyRecord.Status__c", component.find('propStatus').get("v.value"));

var tempRec = component.find("forceRecord");

tempRec.saveRecord($A.getCallback(function(result) {

    console.log(result.state);

    var resultsToast = $A.get("e.force:showToast");

    if (result.state === "SUCCESS") {

        resultsToast.setParams({

            "title": "Saved",

            "message": "The record was saved."

        });

        resultsToast.fire();                

        var recId = result.recordId;

helper.navigateTo(component, recId);

    } else if (result.state === "ERROR") {

        console.log('Error: ' + JSON.stringify(result.error));

        resultsToast.setParams({

            "title": "Error",

            "message": "There was an error saving the record: " + JSON.stringify(result.error)

        });

        resultsToast.fire();

    } else {

        console.log('Unknown problem, state: ' + result.state + ', error: ' + JSON.stringify(result.error));

    }

}));}

})

PROPERTY DIALOG HELPER:

({

    navigateTo: function(component, recId) {

        var navEvt = $A.get("e.force:navigateToSObject");

        navEvt.setParams({

            "recordId": recId

        });

        navEvt.fire();

    }

})

And I'm getting this error message:

Uncaught Unknown controller action 'getPickListValuesIntoList'

Callback failed: serviceComponent://ui.flexipage.components.page.FlexipageControllerV2/ACTION$getPage

With this Stack Trace:

a.H.get()@

doInit()@https://curious-goat-22263-dev-ed.lightning.force.com/one/components/c/PickListValues.js:10:32

Any help would be greatly appreciated.  I don't use Developer Console work in my role, but thought I'd learn and am just ripping my hair out!!

Cheers, Nat

    Hi WDCI Nat,

    Please add controller="PickListController" to the Service component PickListValues.cmp, which calls to PickListController.apxc

    <aura:component controller="PickListController">

        

        <aura:attribute name="sObjectName" type="String" />

        <aura:attribute name="fieldName" type="String" />

        <aura:attribute name="picklistValues" type="Object" />

        <aura:handler name="init" value="{!this}" action="{!c.doInit}" />

    </aura:component>
