Not really expert, but perhaps this might help. I faced similar problems
and this link helped me.

hi,
i've packaged webkitgtk-2.8.3 for nixos and i'm using it with the
gowebkit2 from github.com/sourcegraph/go-webkit2
gowebkit2 requires gojs and gotk3 where both of these pass their
respective go unit tests.
=== question ===
i'm getting this error:
[nix-shell:~/Desktop/projects/webloop]$ go run gowebkit2.go
** (gowebkit2:20348): WARNING **: Error retrieving accessibility bus
address: org.freedesktop.DBus.Error.ServiceUnknown: The name

** (WebKitWebProcess:20355): WARNING **: Error retrieving accessibility

org.a11y.Bus was not provided by any .service files
Load finished.
Title: "Index of /"
URI: http://localhost/
i don't really know how to debug this. anyone an idea how i could get
started? is this a go specific issue?
thanks.
however, the webserver is working from which i query:
[nix-shell:~/Desktop/projects/webloop]$ curl localhost
