There is a duplicate rule on Account object enabled in my org. I have a customize lead convert classic page, in which if I select Create New account option then on click of convert button, it should display the error message of the duplicate rule. I added the below code to be displayed in error messge.

Database.LeadConvertResult leadConvertResult = Database.convertLead(leadConvert);

// if the lead converting was a success then create a task

if (!leadConvertResult.success)

{

PrintErrors(leadConvertResult.errors);

return null;

}

//this method will take database errors and print them to teh PageMessages

public void PrintErrors(Database.Error[] errors)

{

for(Database.Error error : errors)

{

if(error instanceof Database.DuplicateError)

{

Database.DuplicateError duplicateError = (Database.DuplicateError)error;

Datacloud.DuplicateResult duplicateResult = duplicateError.getDuplicateResult();

// Display duplicate error message as defined in the duplicate rule

ApexPages.Message errorMessage = new ApexPages.Message(ApexPages.Severity.ERROR, 'You are creating a duplicate record. We recommend you use an existing record instead.');

System.debug('The error message'+errorMessage);

ApexPages.addMessage(errorMessage);

}

}

}

The above code doesn't provide the simple error message as mentioned in the code. However I recieve a the below error. What is it that I am doing wrong here ?

    Use Try and Catch block and show your error message in exception block.
