Successful push to Grafana Loki API but not showing in the Dashboard

Hello everyone,
this is my first time using Grafana, and currently I tried to use the HTTP API to push log to Loki as suggested from api - Send logs directly to Loki without use of agents - Stack Overflow , and I also had the 204 response status whenever I push the log.

But the problem is, when I tried to look at the dashboard, it only shows the label name and message saying “no volume data”, Do you guys have any idea why this problem occurs? as for the config, I use the default config for Loki and Promtail with addition reject_old_samples: false in Loki config

Here are the request response, and the dashboard :
