NodeRed crash, when setting MC connection

[jinx17]

I AM SORRY, I MADE MISTAKE. THIS WAS MENT FOR node-red-contrib-mcprotocol

BUT MAYBE YOU CAN CHECK THIS ISSUE, SINCE IT USES YOUR LIBRARY?

Every time I set connection parameters NodeRed crashes.
When I restart service, everything works as expected.

Some info for debugging - from start of node-red to crash, when I changed setting of connection node (PLC connection)
PLEASE NOTE I use port 6551, this is not a mistake or error.
