Different messages on the same fabric

[username-pawelg]

I run a node-red dxl implementation, that is running with no issues, but wanted to setup another, that brings me to an error on each message received from broker: Failed to process incoming message: IncompleteBufferError: unable to decode
Both instances are connected to the same broker, running on similar environments (win2k12R2 on both, Node.js v18.14.0 & v18.12.1).
The error led me to message.js _unpackBinObject, in the working instance the buffer.readUInt8(0) returns either 176, 328, 168, the other instance returns 3.
Any help appreciated.
