"coalesce.go:165: warning: skipped value for ..." when installing monochart

[ghost]

When I try to install or template monochart I get the following errors

coalesce.go:165: warning: skipped value for configMaps: Not a table.
coalesce.go:165: warning: skipped value for secrets: Not a table.
coalesce.go:165: warning: skipped value for env: Not a table.
coalesce.go:165: warning: skipped value for env: Not a table.
coalesce.go:165: warning: skipped value for secrets: Not a table.
coalesce.go:165: warning: skipped value for configMaps: Not a table.

The command that I use is:

helm template ./monochart --values ./monochart/values.example.yaml

This is the result:

It seems that the configMaps are generated, but not all the secrets.
