I launched the developer edition, created the My Data app and activated it.  I get this error: Challenge Not yet complete... here's what's wrong: 
The 'MyData' Lightning App was not found.

Any ideas why it's not finding the app.  I see it there and it's activated.

Here are the requirements from Trailhead:
When an Account has the value of 'Prospect' in the Type field, a user will click the 'Submit for Approval' button to launch an approval process. The process will only happen if Type is 'Prospect' and there are more than 500 employees. Upon entry of the process, Type will become 'Pending' and be locked. If approved, Type will be set to 'Customer' and be unlocked. If not approved, Type will be set back to 'Prospect' and will be unlocked.

I've written and rewritten this one over and over, trying different things, but I continue to get this error:


Here is my entry criteria:


I tested it myself and it works correctly for rejected approval requests are don't match the criteria. What am I missing here?
 

Challenge not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Update failed. First exception on row 0 with id 001o000000YgPyRAAV; first error: FIELD_INTEGRITY_EXCEPTION, There's a problem with this country, even though it may appear correct. Please select a country from the list of valid countries.: Shipping Country: [ShippingCountry]

this is the one that updates contacts mailing address when the account shipping address is changed. 

I don't seem to understand the challenge. Do I create a picklist under Accounts?
Can someone help me get started? I am having trouble getting started. I appreciate any help.

Here's the challenge.

Create an approval process that validates when a Prospect Account becomes a Customer.For purposes of local regulation new customers must be approved by the legal team.

When an Account has the value of 'Prospect' in the Type field, a user will click the 'Submit for Approval' button to launch an approval process. The process will only happen if Type is 'Prospect' and there are more than 500 employees. Upon entry of the process, Type will become 'Pending' and be locked. If approved, Type will be set to 'Customer' and be unlocked. If not approved, Type will be set back to 'Prospect' and will be unlocked.

The Account object's Type field must have the following picklist values: Prospect, Customer, Pending. Before creating the approval process, verify the values in your Account object setup
The approval process name must be 'Approve New Account'.
When user click 'Submit for Approval', the approval must be processed if the Type field is set to 'Prospect' and the value of Employees is greater than 500.
Upon entering the approval process, set the Type field to 'Pending' and lock the record.
Normally the approver would be someone else. In this instance, assign yourself to be the approver.
If approved, set the Type field to 'Customer' and unlock the record.
If not approved, set the Type field back to 'Prospect', and unlock the record.

Any idea what could be could wrong ?
 

Hi all, 
I'm a newby in Salesforce so I decided to start learning with the Trailhead. 
I have completed all the challanghes related to the "Getting Started with the Force.com Platform". 
This morning I started with the part 2: "Intro to Visual App Development". 

The fist challenge for Workflow Atuomation is about "Automated Process with Workflow". 
I did the challenge but I receive a failure even if It should seems to run correctly in my Develper Edition Platform. 
Tha error massage received by the check challange button is "Challenge not yet complete... here's what's wrong: Case escalation failed to assign a task to the owner."

I say that all seems to work fine because I edited e case, set up the Priority to High and: 
1) The Escaleted flag was set automatically to true as per the rule action defined
2) I receive a notification about escalation on that case (because I'm the owner of the case as per the task definition field)
3) An activity under the case was automatically created and assigne to me. 

As anyone tha same problem?
Any help would be much appreciated. 
Thank's in advance,
Alvaro.
