Summary

When attaching VSCode to a container, using the Remote - Containers extension, an exception is thrown in the logs, and the extension fails to startup. I'm using Docker Desktop to spin up a PowerShell 7.1.3 container "locally," and then attempting to attach to it.

4. Observe how extension fails to load. Starting PowerShell... text stays active in lower-right corner of VSCode window.

That looks like a pretty clear cut bug! I'll try to reproduce. Thanks for the report.

This will probably be fixed when we finish https://github.com/PowerShell/vscode-powershell/pull/3796 to fix https://github.com/PowerShell/vscode-powershell/issues/2153 and stop using the deprecated field rootPath.

@SydneyhSmith do you have any more detailed logs? Would love to know what the server said.

[SydneyhSmith]

Retested and got it running no problem 😄 -- looks resolved to me

[andyleejordan]
