Evaluate file issue: The export {0} was exported multiple times

[tamaramironov]

Hello! We have recently migrated from VS 2019 to using VS code SDK. Our connectors are buildable and work as expected. However when I try to use "Evaluate current file" feature I get this error for which I can't find any documentation.

    }

It doesn't seem like anything is exported multiple times. Connector works fine and can be tested manually, however this blocks using SDK features. I can't share the source code but want to find out more about this error.

Hey there,

We also recently migrated to VS Code from Visual Studio 2019. Not sure on your build setup, but you need to run Evaluate current file in the ConnectorName.query.pq file and not the ConnectorName.pq file.

Alternatively, if you have a flat folder structure with everything in the connector folder, you can press Ctrl+Shift+B and select Make with PQX; it will build your connector every time.

Hope that helps,

Thank you @geologyrocks, you're right, I tried to use Evaluate current file on the "main" .pq file in my project.
