State not persisted on deployment #13

Open Stadicus opened 1 year ago

Stadicus commented 1 year ago

I use Node Red as part of Home Assistant. The node-red-contrib-persistent-fsm is amazing! It helps control many things like blinds and lights with very few buttons, as it keeps track of the state and can act intelligently with the next press on the same button.

This worked great until about two weeks ago. Suddenly, things started to act weird. For example, blinds started going into the open position in the morning. There was no change in the Node-Red flows at that time. I updated a few things (Home Assistant and Node Red itself), but I'm not sure how closely related that is.

I attach a quick screencast to demonstrate:

This is the flow export from this example:

I'm not quite sure where to start debugging. Maybe I'm doing something wrong? Maybe the Node Red update broke something? Maybe the underlying data storage is no longer working?

Any help would be greatly appreciated.

I've just encountered this myself and found that persisting context to the filesystem makes this work as expected. I added the config from the 'Saving context data to the file-system' section on this page.
