There were errors in the database when exchanging from 1s to the site, from where? What to do?

Question

MySQL

Log:

bitrix/modules/catalog/mysql/product.php
Line: 44
MySQL Query Error: INSERT INTO b_catalog_product(`BUNDLE`, `AVAILABLE`, `TYPE`, `HEIGHT`, `LENGTH`, `WIDTH`, `SUBSCRIBE`, `QUANTITY_RESERVED` `BARCODE_MULTI` `NEGATIVE_AMOUNT_TRACE` `CAN_BUY_ZERO` `VAT_INCLUDED` `, `QUANTITY_TRACE`, `QUANTITY`, `ID`) VALUES('N', 'Y', '1', '0', '0', '0', 'D', '0', 'N ', 'D', 'D', 'N', '0', 'Y', 'N', NULL , 'D', '0', 'S', '25000', 'D', '0 ', '40810')[Duplicate entry '40810' for key 'PRIMARY']

No one can help, as a result, the goods do not really come (prices do not go away, properties are not all).
The exchange itself always worked well, the problem happened when a new nomenclature was connected to download for the site. Where to dig?..

Answer 1

[Duplicate entry '40810' for key 'PRIMARY']

2 entities with the same id

And yet, delete the file, and do not expose the debug information to the public

Answer 2

The errors disappeared, after I restored a fresh backup on the test domain and during the installation process, the database was restored.
