Node-red crash when network is down?

General

Hi,

sometimes Node-red is crashing and I think it's when my network is down. I don' know why there is this behaviour. Here are the logs when the crash occurs.

It crashes on the rbe node, can you post your flow?

What kind of data are you sending data through the rbe node ?

I don't think it is in the rbe node because I had always this error (every 5mn because the flow is running every 5mn) and node-red did not not crash before the network was down. Morever I have just fixed this error by adding a conversion node (JSON string to object) before rbe.
Here is my flow in case of necesary. The flow controls sunset based hour to switch off light.
