I'm trying to create a class that creates a task for an email inbound on a Contact level (but it would be really great if I can create it on Opportunity if you can help me figure it out). I'm currently testing this class on Contact and it isn't working. I'm not very well-versed with Apex. What am I doing wrong? Below is the Apex class I have.

global class CreateTaskEmail implements Messaging.InboundEmailHandler {
 
  global Messaging.InboundEmailResult handleInboundEmail(Messaging.inboundEmail email, 
                                                       Messaging.InboundEnvelope env){
 
    // Create an InboundEmailResult object for returning the result of the 
    // Apex Email Service
    Messaging.InboundEmailResult result = new Messaging.InboundEmailResult();
  
    String myPlainText= '';
    
    // Add the email plain text into the local variable 
    myPlainText = email.plainTextBody;
   
    // New Task object to be created
    Task[] newTask = new Task[0];
   
    // Try to look up any contacts based on the email from address
    // If there is more than one contact with the same email address,
    // an exception will be thrown and the catch statement will be called.
    try {
      Contact vCon = [SELECT Id, Name, Email, AccountId
        FROM Contact
        WHERE Email = :email.fromAddress
        LIMIT 1];
        
      Account a = [SELECT Id, OwnerId FROM Account WHERE Id = :vCon.AccountId];
      
      // Add a new Task to the contact record we just found above.
      newTask.add(new Task(Description =  myPlainText,
           OwnerId = a.OwnerId,
           Record_Type__c = 'Normal Task',
           Priority = 'Normal',
           Status = 'Completed',
           Subject = 'Email: ' + email.subject,
           Type = 'Email Inbound',
           ActivityDate = System.today(),
           WhoId =  vCon.Id));
     
     // Insert the new Task 
     insert newTask;    
     
     System.debug('New Task Object: ' + newTask );   
    }
    // If an exception occurs when the query accesses 
    // the contact record, a QueryException is called.
    // The exception is written to the Apex debug log.
   catch (QueryException e) {
       System.debug('Query Issue: ' + e);
   }
   
   // Set the result to true. No need to send an email back to the user 
   // with an error message
   result.success = true;
   
   // Return the result for the Apex Email Service
   return result;
  }
}

I hope you can help me. Thank you so much!
