Hello,

I'm in the 3rd unit of the Quick Start: Lightning Web Components module where you have to create a Hello World LWC. I have done all steps and the code works (I see the Hello World component on the Homepage in the Playground), but the Verify Step at the end keeps failing with the message:
Step not yet complete in My Trailhead Playground
Make sure you add the 'helloWorld' Lightning web component to the default Home page.

I have deleted the playground and created a new one. I deleted all code and started from the beginning again, but still no success. This is driving me crazy. What is going on?

Can someone help?

I am getting this error: The number of results does not match the number of interviews that were executed in a single bulk execution request.
Here is the apex class I am using, I want to store list<string> data from a json file into a flow variable:

global class par{

    global static List<string> l = new list<string>();
    
@InvocableMethod(label='Get Map' description='Returns the values of Maps')
    global static List<String> CallMap(){
        HttpRequest req = new HttpRequest();
        req.setEndpoint('https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=AIzaSyBOyIQi54LMykmzSOvCuQ2naVvVQEsEfHw');
        req.setMethod('GET');
        Http http = new Http();
        HTTPResponse res = http.send(req);
        JSONParser parser = JSON.createParser(res.getBody());
        while (parser.nextToken()!= null)
        {
            if ((parser.getCurrentToken() == JSONToken.FIELD_NAME))
            {
                    string fieldName = parser.getText();
                    parser.nextToken();
                if(fieldName == 'place_id')
                {
                    string place = parser.getText();
                    system.debug(place);
                    l.add(place);
                	parser.nextToken();
                }else if(fieldName == 'status')
                	{
                    string status = parser.getText();
                    system.debug(status);
                    l.add(status);
                    }
        	}
    	}
        return l;
    }
}

 

 

Create an Apex class that returns a list of contacts based on two incoming parameters: one for the number of contacts to generate, and the other for the last name. The list should NOT be inserted into the system, only returned. The first name should be dynamically generated and should be unique for each contact record in the list.The Apex class must be called 'RandomContactFactory' and be in the public scope.
The Apex class should NOT use the @isTest annotation.
The Apex class must have a public static method called 'generateRandomContacts' (without the @testMethod annotation).
The 'generateRandomContacts' method must accept an integer as the first parameter, and a string as the second. The first parameter controls the number of contacts being generated, the second is the last name of the contacts generated.
The 'generateRandomContacts' method should have a return type of List<Contact>.
The 'generateRandomContacts' method must be capable of consistently generating contacts with unique first names.
For example, the 'generateRandomContacts' might return first names based on iterated number (i.e. 'Test 1','Test 2').
The 'generateRandomContacts' method should not insert the contact records into the database.

I create a class as bellow

public class RandomContactFactory{
   public static List<Contact> generateRandomContacts(integer n,string lastnames){

       list<contact> c= [select  FirstName from contact where LastName =: lastnames limit : n ];
       
       return c;
   }
   
}

but i'm getting error as below

Challenge not yet complete... here's what's wrong: 
Executing the 'generateRandomContacts' method failed. Either the method does not exist, is not static, or did not return the correct set of Contact records.

Please let me know where the issue?
