While going through "Apex web services" in the badge :Apex integration services" i was getting error :"No Apex class named 'DemoController' was found".
Though it got resolved by just creating and saving an empty Apex class "DemoController" i have no clue why this error came at first place,as there were nothing mention about any class naming "DemoController" in the challenge.
WHy ! wHy! whY!!!!!??????

when i am using <ui> tags then its working but the moment i move to lightening tag its throwing above error,. i am new to the salesforce development.

Hey guys trying to get comfortable with the Salesforce CLI, and went to deploy my code changes to my Dev Org but I keep getting the following error message. I checked out the link that they listed, but couldn't seem to figure out what issue was. I modified the JSON with the folder name that I'm trying to deploy, but still had no luck. 
 

Error deploying or retrieving source: The file or directory that you tried to deploy or retrieve isn't in a package directory that's specified in your sfdx-project.json file. Add this location to your "packageDirectories" value, or deploy or retrieve a different file or directory.

Hi!

I started on the Lightning Experience Reports & Dashboards Specialist superbadge and made it all the way to Step 7 (Create the SolarBot dashboard) to get this error message. I started a completely new org for this superbadge module and was wondering if anyone could provide assistance? It's taken me a while to get to this point, so I'd hate to have to start over now. Any help is much appreciated!!

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: ZKSWPWKT

For life of me I can't figure out what this exercise is asking to do.  I was able to modify other reports but this particualr R&D report, Temperature to kWh Research, I'm not able to do.  Error is keep saying, "We can’t find the additional analysis by model being performed on the 'Temperature to kWh Research' report. Remember that you can organize data horizontally and vertically at the same time."




 

Hi, I have completed the test class for the Test Automation logic  challenge. Both my trigger and helper class are getting 100% covered. But the challenge is not complted due to the following error:

Challenge Not yet complete... here's what's wrong: 
The 'MaintenanceRequestHelper' class did not achieve 100% code coverage via your test methods. Make sure that you chose 'Run All' tests in the Developer Console at least once before attempting to verify this challenge.

Can some one point me in the right direction to move forward with the badge completion. TIA !!!

Hi All,

I'm facing this issue, after my org got updated to SPRING 18

I'm trying to complete the Handle Record Changes and Errors module but can't seem to get past the following challenge error:

Challenge Not yet complete... here's what's wrong: 
The 'accEdit' Lightning Component JS Controller does not appear to be setting 'v.recordSaveError' with an error message.

.I've tried many different combinations of sets and am not having much luck.

I've tried several different component.set methods such as this one:
component.set('v.recordSaveError','Error: ' + saveResult.state + ', message: ' + JSON.stringify(saveResult.error));

Any ideas what this module is looking for as a valid solution?

I do see recordSaveError display after being set due to an error.

Thanks.

When I do the Check Challenge, I receive the following error:

Challenge Not yet complete... here's what's wrong:
The Apex controller 'CampingListController' does not exist.

The only thing that I can find in the Forum help documentation is that my code has a campingListController.js and a campingListHelper.js, others have a .js file named camperList.js

Please advise.

Greetings, I've created my external object for the Data Integration Specalist Superbadge and have configured my external ID as seen below, however, the challenge seems to not pass, indicating that the indirect lookup was not properly created. Here's how I set up the projectRef__c field, which was what I used to push data from the external object into the project object in Salesforce. Are there any steps, I need to take. Hope it helps.




 

Hi,
the challenge is as follows :

Create a camping component that contains a campingHeader and a campingList component.
1.The campingList component contains an ordered list of camping supplies that include Bug Spray, Bear Repellant, and Goat Food.
2.The campingHeader component contains an H1 heading style with a font size of 18 points and displays 'Camping List'.

so i made a lightening application named "camping.app" having code :

<aura:application >
    <br/><br/><br/>
    <c:campingHeader/>
    <c:campingList/>  
</aura:application>


where lightening component "campingHeader.cmp" having code :

<aura:component >
    <h1> Camping List </h1>
</aura:component>

for I have "campingHeader.css" having code :
.THIS {
}

h1.THIS {
    font-size: 18px;
}

and lightening component "campingList.cmp" having code :

<aura:component >
    <ol>
       <li>Bug Spray</li>
       <li>Bear Repellant</li>
       <li>Goat Food</li>      
    </ol>
</aura:component>

when i preview the application it is working nice; but when checking the challenge it says :
"Challenge Not yet complete... here's what's wrong: 
The 'camping' Lightning Component does not include either the campingHeader or campingList component."

please help me know where I m doing wrong. Thanx waiting for your reply

Hi,

I can't pass the challenge (https://developer.salesforce.com/trailhead/force_com_dev_intermediate/lex_dev_lc_basics/lex_dev_lc_basics_events). This is the error when check challenge:

Challenge Not yet complete... here's what's wrong: 
The campingList JavaScript controller isn't adding the new record to the 'items' value provider.

I tryed in the browser add new Camping Items and it's working correctly. The item is added to database and the list is updated.

This is my code:

I am stuck at  this point:

                    'Price__c': 0,
                    'Packed__c': false }"/>
    
    <aura:attribute name="items" type="Camping_Item__c[]"/>

Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.

Here is the challenge:
Create a Lightning Component to display a single item for your packing list.

• Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
• Add an attribute named 'item' for type Camping_Item__c.

I created an component named campingListItem and this is the code:

<aura:component >
    <aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
    
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.<my_domain>__Packed__c}"/>
    <ui:outputCurrency  value="{!v.item.<my_domain>__Price__c}"/>
    <ui:outputNumber value="{!v.item.<my_domain>__Quantity__c}"/>
</aura:component>

The error that I am getting is: "Challenge Not yet complete... here's what's wrong: 
The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly."

With this, I tried to create another component, with the name "packingListItem", but It didn't work.

Can anyone help me?
