Converting Lead using Apex trigger on DuplicateRecordItem fails when Account contains a auto-number field

If an account has a custom auto-number field, and the org has a trigger code on DuplicateRecordItem that converts a lead (and attaches to an account that already exists), when conditions for a Duplicate Rule match, the lead conversion fails because ApiEntityObject tries to update the auto-number field in the account.

This causes the lead conversion to fail with an error to the effect of "Update failed. First exception on row 0 with id 001xx000003DcgXXXC; first error: FIELD_INTEGRITY_EXCEPTION, Auto Number field is read-only; no API write access: [Account_Auto_Number__c]"

- Spin up a new org
- Setup -> Accounts -> Fields, and add a custom field that's an auto-number (say, Account_Auto_Number__c)
- Set up a Duplicate Rule ( Setup -> "Duplicate Management" -> Duplicate Rules) which will fire when a duplicate lead is created
-- This rule should let Lead be created and create a DuplicateRecordItem (so no Alert but report should be done on rule on create)-
- Create an apex class using the following code
public class LeadConvert{
public static void FutureFunction(String LeadId,String AccountId,String OwnerId){
Database.LeadConvert lc = new Database.LeadConvert();
list<Database.LeadConvert> LeadConvertList = new list<Database.LeadConvert>();
if (!LeadConvertList.isEmpty()) {
// if one fails, allow others to succeed
list<Database.LeadConvertResult> lcrList = Database.convertLead(LeadConvertList, false);

-Create a trigger for "Duplicate Request Item" ( Setup -> Duplicate Management -> Duplicate Request Item -> Triggers)
trigger DuplicateRecordItemTrigger on DuplicateRecordItem (after insert) {

System.debug('UserDebug: After Insert Duplicate Record Item');
for(DuplicateRecordItem dri:{
Lead currentLead = [select id, company from lead where id=:dri.RecordId];
Account currentAccount = [select id, ownerid from account where];

- Create a new lead which will trigger Duplicate Rule and will result in DuplicateRecordItem being created

Actual result
- This will fail with "FIELD_INTEGRITY_EXCEPTION, Auto Number field is read-only; no API write access: [Account_Auto_Number__c]"

Move lead conversion code to after insert(/update) for Lead

Is it Fixed?
