null: SQL Problem on payment via US API

We currently use Chargeover to process payments through multiple gateways.


This has been working through our Canadian Moneris account for quite some time.


When attempting to connect our US Moneris account via API we receive (Declined) null: SQL Problem on every payment.


I have reset the API key and have setup the US Moneris identically to our Canadian (with different store ID's and API keys) yet cannot get payments to process through our US Moneris.


Our US account is working properly in manual payments as all live payments go through manually.


Need assistance in configuring the API for US Moneris as only our Canadian account is working via API.
