Sleep Regularity Panel

[latetedemelon]

undefined is not iterable (cannot read property Symbol(Symbol,iterator))

I keep getting the following error on the Sleep Regularity Panel and I can't figure out why (data?) If I try to mess with the panel config I get the following:

An unexpected error happened
    Details
    TypeError: Cannot read properties of undefined (reading 'pushEvent')

    at r (http://xxxxxxx.xxx:12358/public/build/5017.830b14490d17e9cbdabb.js:194:122062)
    at div

    at x 

I'm using the latest build and latest panel.

I would like to ask for mor information. Where are you getting the error? In the Grafana panel? what is the influxdb version? 1.x or 2.x? Can you check the raw data as table format in Grafana panel editor? That seems like more of a Grafana panel issue that issue with this project.

• influxdb = 1.8
• grafana = latest
• error is in the grafana panel yes
• yes I can inspect the data. Ranges from null to 3 in 0.5 increments

Not sure what's going wrong here, you can start with a fresh heatmap panel, then use the same query. as the data is there, you can build up the visual gradually using testing and tweaking I hope.

Solved. Some issue with the colour palette. Changing this to Spectral seemed to work:

My panel JSON if it helps anyone.
