I am trying to load templated helm charts like

LocalChartOpts(... values = my_s3_bucket.id.apply(lambda id: renderHelmChart(id)),...).

where

def renderHelmChart( uri ) : 
  loader = FileSystemLoader(/root/path/to/)
  values = Env(loader=loader).get_template(file.yaml).render(uri)
  return yaml.load(values)
