is the command will not work if we give the json file as input in the configmap data ?

apiVersion: v1

kind: ConfigMap

metadata:

name: test-configmap

data:

vendor_config_dev.json: |

{{ .Files.Get "conf/test.json" | indent 4 }}

error: error parsing templates/config-map.yaml: error converting YAML to JSON: yaml: line 8: could not find expected ':'
