        During manifestation

How to reproduce it (as minimally and precisely as possible):
jb install github.com/coreos/kube-prometheus/jsonnet/[email protected]
./build.sh my_build.jsonnet

Removing the line + { ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) } at the end fixes the issue but obviously excludes grafana from the result.

I aslo met this issue, I exported an json file of my dashboard from grafana UI, then I edit the jsonnet followed the docs, when I executed ./build.sh my-test.jsonnet then this error raised, not sure how to fix this? Could anyone can help? Thanks very much.

According jsonnet docs:
std.encodeUTF8(str)
Available since version 0.13.0.

Maybe it's the reason ?

I remove the old jsonnet snap remove jsonnet and install a new one by go get github.com/google/go-jsonnet/cmd/jsonnet the version is v0.16.0 and build is ok.
