Problem with the "Apex Web Services" unit

Hi everyone,

i'm getting the following error after the system checks the challenge:

"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.QueryException: List has no rows for assignment to SObject"

I already tested it via Apex and via REST Explorer in Workbench, the code seems fine to me:

@restResource(urlMapping='/Account/*/contacts')
global class AccountManager {
	
    @httpGet
    global static Account getAccount(){
        RestRequest request = RestContext.request;
        String accountId = request.requestURI.substringBetween('/Account/' , '/contacts');
        
        Account result = [SELECT Id, Name, (SELECT Id,Name FROM Contacts) FROM Account WHERE Id = :accountId];
  
        return result;

    }
    
}


Can somebody help me with this?

Thank you,
Fabio

AccountManager Apex Class


@RestResource(urlMapping='/Accounts/*/contacts')
global class AccountManager {
    @HttpGet
    global static Account getAccount() {
        RestRequest req = RestContext.request;
        String accId = req.requestURI.substringBetween('Accounts/', '/contacts');
        Account acc = [SELECT Id, Name, (SELECT Id, Name FROM Contacts) 
                       FROM Account WHERE Id = :accId];
        return acc;
    }
}


TEST CLASS

@isTest
private class AccountManagerTest {

    private static testMethod void getAccountTest1() {
        Id recordId = createTestRecord();
        // Set up a test request
        RestRequest request = new RestRequest();
        request.requestUri = 'https://na1.salesforce.com/services/apexrest/Accounts/'+ recordId +'/contacts' ;
        request.httpMethod = 'GET';
        RestContext.request = request;
        // Call the method to test
        Account thisAccount = AccountManager.getAccount();
        // Verify results
        System.assert(thisAccount != null);
        System.assertEquals('Test record', thisAccount.Name);

    }

    // Helper method
        static Id createTestRecord() {
        // Create test record
        Account TestAcc = new Account(
          Name='Test record');
        insert TestAcc;
        Contact TestCon= new Contact(
        LastName='Test', 
        AccountId = TestAcc.id);
        return TestAcc.Id;
    }      
}

After saving it "Run All" test from developer console. It'll help you to clear the challange.

Mark it as best answer please.

Nevermind, I found the problem.

My URI was wrong, it had "Account" instead of the requested "Accounts".

Challenge Not yet complete... here's what's wrong: 
Executing the 'AccountManager' method failed. Either the service isn't configured with the correct urlMapping, is not global, does not have the proper method name or does not return the requested account and all of its contacts.

You can let me know if you have any other problem regarding trailhead badge complition.

Just a remark, I advise you to use:
'/services/apexrest/Accounts/'
 instead of 'https://na1.salesforce.com/services/apexrest/Accounts/' because hard-coding the instance will be problematic when delivering to another environment.
Ivan GnedyshevIvan Gnedyshev

Thanks. Naveen!

Though, I still don't get it why my code coverage was only 85% (return accountTest wasn't covered). I had almost the same code!

P.S. Of course my class was working as I tested it myself with Workbench and Query Editor

        return result;
    }
    
}
Test class: 
@isTest
private class AccountManagerTest {

    private static testMethod void getAccountTest() {  
        
        Id recordId = createTestRecord();

Hi - I just set up a new Dev org to do this segment and am having a problem with the url. Any tips?

The base url for the home Sales app is: https://na59.lightning.force.com/one/one.app#/home

I put in the first piece of APEX thats in the segment and used workbench to hit it with the post example but get a 404 error. The uri I am hitting is:

//na59.lightning.force.com/services/apexrest/Cases/
