Unable import Dashboard after build tailscale container from Dockerfile

[corasaniti]

I was unable to import the dashboard after build successful only Docker tailscale container...

After create correctly InfluxDB datasource in Grafana and import this dashboard
https://github.com/xinmans/docker-tailscale-monitor/blob/main/docker/grafana/provisioning/dashboards/tailscale_monitor.json

I get the following error
Datasource with id:2L-Vpefnz does not exist

I tried setting the datasource manually with no success. You probably have you need to export the dashboard for external use
(see screenshot)

Also I have another problem: in the influx DB after 3-4 detections the Relay901latencyMs value is always 0 for all hosts and therefore the graph is flat...

Do you have any suggestions
