How to Display custom error code and custom error message in catch block? [closed]

Question

@RestResource(urlMapping='/AccountThrowErrorCode/')
global class AccountError {
    @HttpPost
    global static Account doPost(){
        string jsonResponse='';
        RestRequest request = RestContext.request;
        RestResponse response = RestContext.response;
        String requestBody = System.RestContext.request.requestBody.toString();
        AccWrapperError acc = (AccWrapperError)JSON.deserialize(requestBody,AccWrapperError.class);

        try{
            if(string.isBlank(acc.Name) || string.isBlank(acc.phone))
                throw new accountCodeException('Fields should not be Empty');
        }
        else{
            Account accRecord = new Account();
            accRecord.Name = acc.Name;
            accRecord.Phone = acc.Phone;
            accRecord.Rating = acc.Rating;
            insert accRecord;
            return accRecord;
        }
        catch (accountCodeException e) {
            accountCodeException aa;
            throw new accountCodeException('New error '{errorCode:201,errorMessage:+e.getMessage()});
        }
    }

    public class accountCodeException extends Exception {
    }
}

you can try using a new apex class, with two properties: code and message:

public class CustomExceptionResponse {
    
    private String code;
    private String message;
    
    public CustomExceptionResponse(String code, String message) {
        this.code = code;
        this.message = message;
    }
}

and then when you throw your custom exception, serialize the object, something like this:

catch (Exception e) {
   String error = JSON.serialize(new CustomExceptionResponse('201', 'Your Custom Message Here plus: ' + e.getMessage()));
   throw new accountCodeException(error);
}

Hope this helps!
