Node-Red exception

For some time I have at random time's this in my node-red log file.

And I can not figure out what is causing it. It seems to be one of Victron own nodes but what exactly?

Thanks. Do you mind sharing your flows with me (you can mail them if you prefer that) so I can take a closer look? And can you tell me what hardware is connected?

My VRM portal id is: 48e7da8999bd

So you can look there what hardware I have.

And I have a lot of flows together 6 or more tabs. So I can export them and compress to zip file but where do I find your email to mail them?

Thank you. With the vrm id I was able get de device list. And am also able to fetch the flows, so mailing is not needed. You do indeed have quite a lot of flows.

I am fairly sure that the problem will be solved with the next release candidate which will carry version 1.4.25 of node-red-contrib-victron. But that is of no help right now.

I will try to replicate the reproduce your issue on my test system and report back. Note that that might take a few days.

I did some checks on different systems and am quite sure that it is one of the connected devices that is causing it. Question is which one. I checked some of the devices that I have around (grid meter, shunts and mulitplus). But those do not seem to cause it. Do you mind enabling remote support on your system, so I can login, check the logging and the dbus and hopefully locate the cause?

I have enabled Remote Support in my system, so You can log in if you want :)

What I found is that ModBus TCP Services I have three different device with the same ID

Lynx Shunt 1000a ve.Can - Unit id: 100

com.victronenergy.system - Unit id: 100

com.victronenergy.hub4 - Unit ID: 100
