Hi
This error appears went I deploy the program, and then the program stops working. When this happens I need to restart node-red, and then the program works again. Maybe someone had this problem in the past.
I am working with the Asset Monitor.
Thanks
Unfortunately we haven’t seen this issue before. That looks like for some reason that the config node becomes unset from memory somehow.
Do any errors display in your console that you used to start Node-Red when this error occurs?
Check your configuration nodes and look for one that isn’t being used or anything strange? You can find config nodes through the context menu in the top right of the UI > Configuration Nodes
Hi, Jacob. I saw something weird and I delete all the unused serial configurations, but the problem continues.
How I can restart all the memory?
Thanks
Restarting Node-Red clears all memory and its really the only reliable way.
Unfortunately that error message isn’t any more informative.
Can you post your Node-Red export (Context menu in top right, Export, copy to clipboard, paste it here) or if it contains sensitive material you can send it to us through our contact form: https://ncd.io/contact-us/technical-support-for-ncd-industrial-devices/

Hmm, its possible that the modem is getting data it doesn’t understand and may be trying to treat it as a configuration packet. Can you set your “Serial Device for Config” setting on that wireless device to the Serial 2 Config Node and see if the problem continues or if this reveals more about the actual issue?
I do it, but error remains.
Don´t worry this fail is just went I make a full deploy, but is not serious, I can live with that.
Thanks
We also face the exact problem in various computers and with very basic flows (even when having only a USB modem and a sensors nodes-flow below). The error comes after every deployment and node red needs to be restarted.

The problem resists on both Windows and Linux deployments. Since we haven’t faced it before, maybe it was caused by a recent update to the library?
And let me add tht the error appears after every single “deploy”(ment) and once the error appears the system becomes inoperable ie not able to receive data from sensors.
Its possible, we remapped specific keys in memory to better differentiate between ethernet modems, but it shouldn’t have interfered with the Serial based modems. I’ll grab a few modems today and run a diag on the references for each type.
Could you let me know what version of NodeJS and Node-Red you’re running on the windows or linux box?
