Hello!
There was a change in platform version 11.18.0 that affected this extension: "Improved the DLL loading mechanism of Platform Services and Applicational Runtime for Database Connectors/Plugins and their referenced DLLs. This may bring breaking changes to some third-party/custom Database Connectors/Plugins (built with the Database Connector SDK) and some assets available on Forge. Find more about these breaking changes here. (R11BRT-173)".
This extension relied on the platform's database drivers, which now are only available when an external database connection for the database exists. Including the drivers in this extension can lead to conflicts with the platform drivers, so it's not a straightforward fix.
If you read through the details of this breaking change there's a workaround that doesn't involve changing the extension:
- Identify the assembly that's failing to be loaded in the list above.
- Create a new External Database Connection and chose the DBMS identified on the list.
- Don't test it and then save it. This will be a dummy connection, used only to recreate the files. It doesn't need to be assigned to an extension.
- Republish the app that was having the errors.
I hope this helps.
