Hi,

Thank you for reaching out. Please note RDS does not come bundled with third-party ADO.NET data providers. Because of that, it is required:

  1. Copy the provider's DLL to the server's Bin folder or install it to the GAC.
  2. Do the same for all transitive assemblies this data provider may rely on.
  3. Update binding redirects in web.config in case there's a mismatch between what the provider uses VS what the server uses.

For more information, please refer to the following ticket where a similar issue of running the Npgsql provider (v4.0.X) was discussed: after upgrading report server to 22.2.3, data models will not load.

I hope it helps. Keep up updated on your results.

Regards,
Yaroslav
