Hi everyone,

I’m stuck for several days trying to get Grafana dashboards to provision on my Luckfox Lyra Ultra PoE  
I’m running Grafana 11.2.2 ARMv7 on a \*\*Luckfox Lyra Ultra PoE\*\* board:

- SoC: Rockchip RK3506 (ARMv7l)
- OS: Buildroot + BusyBox (Luckfox\_Lyra\_Ultra\_W\_EMMC\_250717 image)

Everything works perfectly except the load of the dashboard:

- Node Exporter 1.8.2 → :9100
- Prometheus 3.7.3 → :9090 (scrapes localhost:9100)
- Grafana 11.2.2 ARMv7 → :3000
- `defaults.ini` loaded (`Config loaded from …`)
- Provisioning starts and finishes
- `dashboard.yml` correct
- JSON file present, permissions 644, UTF-8 clean (no BOM, no CRLF, hexdump OK)

The json structure follow the recommendations:

```auto
{
  "dashboard": {
    "id": null,
    "uid": "luckfox-health-1",
    "title": "LuckFox Health",
    "tags": ["luckfox"],
    "timezone": "browser",
    "schemaVersion": 38,
    "refresh": "30s",
    "version": 1,
    "panels": [...],
    "templating": { ... }
  },
  "folderId": 0,
  "overwrite": true
}

```

I get Any idea what could cause this on Buildroot/BusyBox?  
Any help would be greatly appreciated

Try without nested dashboard field:

```auto
{
    "id": null,
    "uid": "luckfox-health-1",
    "title": "LuckFox Health",
    "tags": ["luckfox"],
    "timezone": "browser",
    "schemaVersion": 38,
    "refresh": "30s",
    "version": 1,
    "panels": [...],
    "templating": { ... }
}

```

Thank you very much [ebabeshko](https://community.grafana.com/t/luckfox-lyra-ultra-poe-grafana-11-2-2-armv7-dashboard-title-cannot-be-empty-with-100/159226/2)!  
Removing the nested “dashboard” field did the trick — the dashboard now provisions correctly
