Rendering a map into a template with {{ toYaml .Values.resources | indent 8 }} produces YAML that starts on the same line as the key, because toYaml emits no leading newline and indent does not add one. The result is a manifest that fails to parse with an error pointing at a line that looks correct.
nindent prepends a newline before indenting every line by the given width, which is what the surrounding template almost always needs. The idiomatic form is resources: on its own line followed by {{- toYaml .Values.resources | nindent 8 }}, with the leading dash trimming the preceding whitespace and newline.
A second detail: toYaml on an empty or nil value renders the literal null, which produces resources: null rather than omitting the key. Guard with {{- with .Values.resources }} so the block is skipped entirely when unset. nindent has been available since Helm 3 shipped the Sprig function set and is stable.
