Customer upgraded to Sage 50 2022 and enabled Remote Data Access - Integration dies SLALockFailure

SOLVED

Greetings all,

Our ERP product integrates with Sage 50 for posting Invoices and Purchase Orders from our application to Sage.

One of our customers just upgraded their Sage 50 to the 2022 release (which I don't expect caused any issues) and also purchased and enabled the "Remote Data Access" feature. This feature seems to be causing issues with our integration.

When we attempt to communicate in to Sage, we get an exception with the message "Unexpected Remote Data Access return value: SLALockFailure".

Do we have to put the Sage 50 client in some special mode in order to allow our integration to communicate with Sage 50 in remote data access mode?
