Steps to Reproduce:

I don't know how to reproduce it, because it's OK before this error.

After I debug dev container extension, I found the following lines are the problem:

 ...t.map((o) =>
      Nt.workspace.findFiles(
        new Nt.RelativePattern(
          o.with({ path: sd.posix.join(o.path, '.devcontainer') }),
          '{devcontainer.json,*/devcontainer.json}'
        )
      )
    ),

When I changed it to

...t.map((o) =>
      Nt.workspace.findFiles(
        new Nt.RelativePattern(
          o,
          '.devcontainer/devcontainer.json'
        )
      )
    ),

It's working then.

Anyway, the error message prompted is misleading, since the real problem is the extension cannot find the devcontainer.json.
