Docs local preview fails on Windows PowerShell and Hugo 0.92.1

[abdollahShahid]

I tested the docs local preview workflow on Windows PowerShell from a clean upstream worktree.

Screenshot 1 shows the clean test setup. I created a separate worktree from origin/master, entered it, and confirmed git status showed nothing to commit, working tree clean.

Screenshot 2 shows the first failure. Running the documented command:

make run/site

fails in PowerShell because grep is not recognized. The command then continues with an empty RELEASE value and fails at Makefile:206.

Screenshot 3 shows the Hugo version I used for the direct test:

hugo v0.92.1 ... extended windows/amd64

Screenshot 4 shows the second failure. After setting the release manually and running Hugo directly:

$env:RELEASE = "v0.55.0"
& "$env:TEMP\hugo-0.92.1\hugo.exe" server --source=docs

the docs site starts building, but fails with:

can't evaluate field IsServer in type interface {}

Screenshot 5 shows the worktree was still clean after testing, so this does not appear to be caused by local docs changes.

Expected behavior should be The documented local docs preview workflow should work on Windows, or the docs should explain the supported Windows workflow and required tools. My Envirnment is Windows PowerShell with hugo v0.92.1 extended windows/amd64.
