      Check the syntax just replace your test class with the following code :
      @isTest
      public class BatchLeadConvertTest {

      @isTest
      static void sanity(){
      Lead l = new Lead(
      FirstName = 'Bobby',
      LastName = 'Bobson',
      Company = 'Salesforce'
      );
      insert l;
      BatchLeadConvert job = new BatchLeadConvert();
      Test.startTest();
      Id jobId = Database.executeBatch(job);
      Test.stopTest();
      System.assertEquals(0, [SELECT NumberOfErrors FROM AsyncApexJob WHERE Id = :jobId].NumberOfErrors);
      }

      @isTest
      static void customObjectCreatedFromEventTrigger(){
      if(!isUpdatedForEvents()){
      return;
      }
      Lead errLead = new Lead(
      LastName = 'Astro DoNotConvert',
      Company = 'Trailhead'
      );
      insert errLead;

      BatchLeadConvert job = new BatchLeadConvert();
      Test.startTest();
      Id jobId = Database.executeBatch(job);
      try{
      Test.stopTest();
      }catch(DmlException ex){ /* don't fail this test if there were errors in the batch job - we want that */ }
      Test.getEventBus().deliver();

      List errorLogs = [SELECT id, StackTrace__c, Records__c FROM BatchLeadConvertErrors__c];
      System.assertEquals(1, errorLogs.size(), 'Expected errors converting DoNotConvertLeads');
      System.assert(errorLogs[0].Records__c.contains(errLead.Id), 'Expected "Astro DoNotConvert" Lead to fail to convert');
      }

      static Boolean isUpdatedForEvents(){
      ApexClass cls = [SELECT Body FROM ApexClass WHERE Name = 'BatchLeadConvert'];
      return cls.body.containsIgnoreCase('Database.RaisesPlatformEvents');
      }
      }

    Hello Shivangi ,

    BatchApexErrorEvent values are not correctly assigned to BatchLeadConvertErrors__c fields in your trigger .
    In trigger , most probably you have assigned Records__c to RequestId but it should be assigned to JobScope .

    You may replace your trigger code by below lines of code :

    trigger BatchApexErrorTrigger on BatchApexErrorEvent (after insert) {
    list leadConvertErrorList = new list();
    for (BatchApexErrorEvent e : trigger.new) {
    leadConvertErrorList.add(new BatchLeadConvertErrors__c(AsyncApexJobId__c=e.AsyncApexJobId,Records__c=e.JobScope,StackTrace__c=e.StackTrace));
    }
    system.debug('*****leadConvertErrorList ***'+leadConvertErrorList);
    if (leadConvertErrorList.size() > 0 ) {
    Insert leadConvertErrorList;
    }

    }

    I got passed in the Platform Developer I (WI20) (PDI) exam recently. I am here to share my experiences and study resources related to this exam.
    There are many free and paid study resources on the internet to help you practice and pass the Platform Developer I (WI20) exam.
    few resources that I personally used to prepare myself is valid practice material like up-to-date PDI exam training questions, reading community reviews and discussions regarding exam experience of different candidates will be helpful.

Maintain Your Platform Developer I Certification for Winter ’25

  Make Invocable Actions Easier to Configure with New InvocableVariable Modifiers Simplify the configuration of invocable actions using new modifiers from Salesforce. Both the defaultValue and placeholderText modifiers will appear in Flow Builder for the Action elements that correspond to an invocable method. Here’s how to use them. defaultValue Modifier : Set a default value for an input parameter. When the action is used, the input parameter will have a predefined value unless changed by the user. placeholderText Modifier : Set custom placeholder text for an input parameter. Text can provide examples or additional guidance to help users understand what to enter in the input field. Accessing these modifiers in Flow Builder makes it easier to configure and use the actions within your flows. This change applies to Lightning Experience and Salesforce Classic in Performance, Unlimited, Developer, Enterprise, and Database.com editions.
