Invalid configmap generation for helm chart grafana - kubernetes-helm

Question

I'm trying to create a configmap
I use this values ​​file. Example :
datasources:
datasources.yaml:
apiVersion: 1
datasources:
- name: Prometheus
type: prometheus
uid: prometheus
url: http://prometheus-kube-prometheus-prometheus.monitoring:9090
- name: Thanos
type: prometheus
uid: thanos
url: http://thanos-query.monitoring:9090
- name: Tempo
type: tempo
uid: tempo
url: http://tempo-tempo-distributed-query-frontend.monitoring:3100
jsonData:
httpMethod: GET
datasourceUid: loki
lokiSearch:
datasourceUid: loki
serviceMap:
datasourceUid: prometheus
search:
hide: false
nodeGraph:
enabled: true
- name: Loki
type: loki
uid: loki
url: http://loki.loki:3100
jsonData:
maxLine: 1000
derivedFields:
- datasourceUid: tempo
matcherRegex: "traceID=(\\w+)"
name: TraceID
url: "$${__value.raw}"
...
But when creating configmap i get wrong CM
Example :
datasources.yaml: |
apiVersion: 1
datasources:
- name: Prometheus
type: prometheus
uid: prometheus
url: http://prometheus-kube-prometheus-prometheus.monitoring:9090
- name: Thanos
type: prometheus
uid: thanos
url: http://thanos-query.monitoring:9090
- jsonData:
datasourceUid: loki
httpMethod: GET
lokiSearch:
datasourceUid: loki
nodeGraph:
enabled: true
search:
hide: false
serviceMap:
datasourceUid: prometheus
name: Tempo
type: tempo
uid: tempo
url: http://tempo-tempo-distributed-query-frontend.monitoring:3100
- jsonData:
derivedFields:
- datasourceUid: tempo
matcherRegex: traceID=(\w+)
name: TraceID
url: $${__value.raw}
maxLine: 1000
name: Loki
type: loki
uid: loki
url: http://loki.loki:3100
I did everything according to the documentation, but the second day I can not understand what is the reason for the incorrect creation.
As a result, I'm trying to do a Loki search to work with Tempo
