This is also related to this change I get with previous version

WARN deprecated: .Site.IsServer was deprecated in Hugo v0.120.0 and will be removed in a future release. Use hugo.IsServer instead.

As it seems to have been removed now leading to error

executing "_default/list.html" at <$.Site.IsServer>: can't evaluate field IsServer in type page.Site

FWIW it has been removed in 1.37

ERROR deprecated: .Site.IsServer was deprecated in Hugo v0.120.0 and will be removed in Hugo 0.137.0. Use hugo.IsServer instead.
ERROR deprecated: .Site.LastChange was deprecated in Hugo v0.123.0 and will be removed in Hugo 0.137.0. Use .Site.Lastmod instead.

We are currently building with 0.131.0 so that we have a version without ERROR on those.
