Desjardins module: Duplicate request error
Last Updated 4 years ago

If you encounter this error when trying to process a payment:
"A duplicate request has been submitted. Please contact the supplier for assistance. Do not retry the request."
 
...follow these instructions to get your payments to process. The reason this error occurs, is due to the payment method requiring a unique identifier for each incoming payment.
 
** First and foremost, remember to refresh the cache (System > Cache Management) when you install or update anything on the backend of your site. If you still encounter the error mentioned above, continue reading for further instructions.
 
1. Log into MySQLof your site.
[root@localhost ~] # mysql -uroot -pasdf1234
mysql >
2. Change your database to the one that the site with the Desjardins module uses.
mysql > use database1
Database changed.
mysql >
3. We need to change the increment value for the eav_entity_store table to a different numeric value (anything other than the value shown in the first table).
mysql >  select * from eav_entity_store;
+-----------------+----------------+----------+------------------+-------------------+

| entity_store_id | entity_type_id | store_id | increment_prefix | increment_last_id |

+-----------------+----------------+----------+------------------+-------------------+

|               1 |              4 |        1 | 1                | 100000001         |
+-----------------+----------------+----------+------------------+-------------------+
mysql > update eav_entity_store set increment_last_id = 12300000001;
+-----------------+----------------+----------+------------------+-------------------+
| entity_store_id | entity_type_id | store_id | increment_prefix | increment_last_id |

+-----------------+----------------+----------+------------------+-------------------+

|               1 |              4 |        1 | 1                | 12300000001       |
+-----------------+----------------+----------+------------------+-------------------+
4. Attempt another transaction on your site and it should correctly redirect you to the Desjardins site.
