Node-RED crashing when deploying modbus read serial node

[turfpal]

Which node-red-contrib-modbus version are you using?

5.26.0

What happened?

When I configure a modbus read node as serial and deploy. Node-RED instantly crash and goes into infinite boot-loop. Running Node-RED in docker on Wago CC100. Tried the same on two different Wago CC100s, with same result.

Just for info, I've tried several other RS-485 devices and configurations all with the same outcome.

Server

Modbus-Server Node

How can this be reproduced?

Add a single modbus read node and a debug node, configure as serial, then deploy.

What did you expect to happen?

Node-RED not crashing and be able to read the output of the modbus node.

Thanks Allesandro!
However, I always get a segmentation fault after updating to [email protected]. Any idea what's going wrong?
