This works though when in an escalated shell, so that is the current workaround.

With an escalated shell I still get an error about no configuration, let me reboot and I'll capture it here.

Running as Administrator, in Developer Mode:

--- FAIL: TestAccResourceID (1.89s)
    testing_new.go:94: terraform failed: exit status 1
        
        stderr:
        
        Error: No configuration files
        
        Apply requires configuration to be present. Applying without a configuration
        would mark everything for destruction, which is normally not what is desired.
        If you would like to destroy everything, run 'terraform destroy' instead.

Hmm, it works on my machine with just a "Run as administrator" Powershell instance. Don't think I'm using the developer mode though maybe.

OK, so after some fun debugging, we figured this one out. Probably. It looks like the root cause is hashicorp/terraform#25233 doesn't apply just to plan files, but also to the config directories if you pass them in manually. Which... we are.

We confirmed this works in 0.13.0-beta2 and 0.13.0-beta3, which makes sense, as hashicorp/terraform#25233 was fixed in 0.13.0-beta2.

I've also confirmed that this works in 0.12.26 and higher if we use a relative path when specifying the config directory, instead of an absolute path. Given that hashicorp/terraform#25233 is about specifying things by relative path, this seems to further point to it as the root of the issue.

Given that we can fix this SDK-side without too much effort, I'm proposing we move this back into the 2.0.0 release and instead modify the SDK to use relative paths for the config files. I'll have a PR up for that shortly.
