[16.0] Odoo Error While using Account Chart update - Expected singleton

[SIC-brunorocha]

Hello, I´m new to using the module, but I get a Odoo Error when using it.

Module
account_chart_update

Describe the bug
File "/home/odoo/src/user/account_chart_update/wizard/wizard_chart_update.py", line 621, in find_account_by_templates
return result.id
File "/home/odoo/src/odoo/odoo/fields.py", line 5090, in get
raise ValueError("Expected singleton: %s" % record)
ValueError: Expected singleton: account.account(18, 20, 220, 222, 36, 38, 40, 236, 242, 42, 44, 46, 244)

To Reproduce
Open Update chart of account, select a chart template, press next.

Expected behavior
I believed is expected to move from Configuratioon, to Select Records To Update State.

This happens when there are duplicate accounts found for the same template (matching code or name) IIRC.

You have to deduplicate them in the chart of accounts. Look them up by id i.e. "18" and "20" probably have something in common.

Hum....Tanks I will check.
It should have a manual this OCA module
