Something weird is going on. I get problems for every gqlparser version down to v2.2.0:

#!/bin/bash
# exit if any command fails:
set -e

array=( $(git log v2.2.0..v2.3.0 --pretty=format:"%h") )

for i in "${array[@]}"
do
	echo "$i"
    go get -d github.com/vektah/gqlparser/v2@$i
    go mod tidy
    cd example
    go get -d github.com/vektah/gqlparser/v2@$i
    go mod tidy
    cd ..
    go generate ./... && cd example && go generate ./... && cd ..
done

It looks like the vektah/gqlparser#168 PR by @wilhelmeek causes a problem. Hopefully he can make another run at that work in a later PR as I'm going to revert it.

Coverage remained the same at 74.997% when pulling 0ec978a on update_parser into c161ab3 on master.

So I needed to revert the vektah/gqlparser#168 PR by @wilhelmeek and cut a v2.3.1 over there as it caused problems here and in genqlient.

Upgrading the gqlparser to v2.3.0 causes these problems:
