Remote write to AMP using sigv4

Prometheus server
1

Hi, I’m trying to use the prometheus-community chart to write to AMP workspace. I’ve created the ingest role and trying to use the following values.yaml:

serviceAccounts:
  server:
    name: "amp-iamproxy-ingest-service-account"
    annotations:
      eks.amazonaws.com/role-arn: "arn:aws:iam::<arn>:role/amp-iamproxy-ingest-role"
server:
  remoteWrite:
    - url: "https://aps-workspaces.us-east-1.amazonaws.com/workspaces/ws-<id>/api/v1/remote_write"
      sigv4: 
        region: "us-east-1"
      queue_config:
        max_samples_per_send: 1000
        max_shards: 200
        capacity: 2500
  extraArgs:
    log.level: "debug"

When trying to use these values seems like it is not able to create the configmap as it is not expecting to recieve the sigv4.region this way:

level=error ts=2024-06-23T10:14:08.263Z caller=main.go:881 err="error loading config from \"/etc/config/prometheus.yml\": one or more errors occurred while applying the new configuration (--config.file=\"/etc/config/prometheus.yml\")"

When leaving sigv4 empty:

ts=2024-06-23T10:10:50.490Z caller=dedupe.go:112 component=remote level=error remote_name=776091 url=https://aps-workspaces.us-east-1.amazonaws.com/workspaces/ws-<id>/api/v1/remote_write msg="non-recoverable error" count=146 err="server returned HTTP status 403 Forbidden: {\"message\":\"Missing Authentication Token\"}
