Hello, and thank you for making this beautiful piece of software.
I have run out of options trying to figure out this problem. I have searched the forums for similar old posts but none of the solutions seem to work for me, or i am missing something, and searching the quoted error strings i am getting on google fetches me only one single result which is from a failed build log on netlify - not mine or related to my project at all.
So… here I am seeking your help.
The error I get (in short)
can't evaluate field Hugo in *hugolib.PageState
The longer error log:
Summary

The template partial snippet that seems relevant to this is below:
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta content='text/html; charset=utf-8' http-equiv='content-type' />
{{ partial "open_graph.html" . }}
{{ .Hugo.Generator }} <!-- this line seems to be the one, that's all i can tell from the error message -->
My hugo env below:
> hugo env
hugo v0.95.0-9F2E76AF+extended windows/amd64 BuildDate=2022-03-16T14:20:19Z VendorInfo=gohugoio
GOOS="windows"
GOARCH="amd64"
GOVERSION="go1.18"
I have tried to build the exact same code on a linux machine as well and get the exact same error messages (only different file paths).
Hugo env for the linux machine:
Summary
hugo v0.95.0-9F2E76AF+extended linux/amd64 BuildDate=2022-03-16T14:20:19Z VendorInfo=gohugoio
GOOS="linux"
GOARCH="amd64"
GOVERSION="go1.18"
If this doesn’t seem like something obviously missing or wrong in configuration (since this same template is known to work for someone else, with the difference mainly being in config that I setup separately without knowing much of what i am doing but following the reference from here… and another source mentioned in the config file below).
Below is the full copy of my config (i was getting the same error before adding all of the content after the theme in this config as well.):

There are many similar posts in the forum with similar topic “Can’t evaluate field x… in type *hugolib.pageState” but trying solutions posted there did not resolve my problem.
Thanks for your time and help.
