Cannot set maxLines in Loki datasource

[modzilla99]

What happened:
When installing the Loki stack, I try to set the maxLines option to 5000. But that option never gets set correctly in Grafana.

What you expected to happen:
Grafana should should the option changed to 5000 or rather the value set in the datasource yaml.

How to reproduce it (as minimally and precisely as possible):
Deploy the loki stack with the following values:

helm install loki grafana/loki-stack -f values.yaml

grafana:
  enabled: true
  datasources:
    datasources.yaml:
      apiVersion: 1
      datasources:
      - name: Loki
        type: loki
        url: http:https://loki-headless:3100
        jsonData:
          maxLines: 5000

Anything else we need to know?:
I tried with the version provided by the stack and the newest grafana (9.3.6 and 8.5.16)

Environment:

• Grafana version: 8.3.5
• Data source type & version: Loki
• OS Grafana is installed on: Kubernetes
• Grafana plugins: -

@modzilla99 ,I am using below configs under loki, maxLines: 5000 is working for me,

datasource:
    jsonData: "{maxLines: 5000}"

.

If you want add it using grafana you need to change the datasource name, otherwise it will conflict with default Loki.

grafana:
  enabled: true
  datasources:
    datasources.yaml:
      apiVersion: 1
      datasources:
      - name: Loki-test
        type: loki
        url: http:https://loki-headless:3100
        jsonData:
          maxLines: 5000
