Labels visible, but logs are not

Grafana Loki
1

I am trying to use Loki and Grafana to store logs for some HTTP events on my Node server. To test beforehand I created a POST request in Postman and sent it to https://<user>:<apiKey>@logs-prod-<database>.grafana.net/loki/api/v1/push. This gives me a 204 response.

In my Explore tab I have the Loki datasource selected, and I am able to see the labels (app & level) from this request, but I am not able to see any logs. I have tried modified the date range, but that did not help. Is there something wrong with my request?

{
  "streams": [
    {
      "stream": {
        "level": "info",
        "app": "app"
      },
      "values": [
        [
          "1720699969000000000",
          "test"
        ]
      ]
    }
  ]
}

Are you saying that you get logs from API call but not from Grafana Explore? Share a screenshot please? What query are you using in Explore? There is also a query inspector which will show you the API call Grafana performs to Loki based on your query, take a look at that and perform the same API call and see what happens.
