I’m encountering an error where on occasion the timeseries component throws this exception.

I’m running a nightly build ( b2019091302 ) of Ignition.

Any updates triggered on the component makes the error immediately go away, even if nothing changes.

Here’s a few screenshots:

Hi @paul.longtine, a fix for this error went out in yesterday’s (9/25) nightly build. If you’re able, please update and post back if you’re still seeing that error.
