"TypeError: Cannot read properties of undefined (reading 'replace')"

[u20p17]

Hello @Darklyte, I found your great work and I am currently trying to use it with my roborock (using the https://github.com/humbertogontijo/homeassistant-roborock integration instead of the Mi integration).

I changed your flow like you describe it in the instruction and also in the comment nodes, but I get an error in the 'pull variable' function node: "TypeError: Cannot read properties of undefined (reading 'replace')"

it seems that msg.vacuum is not set correctly (--> is undefined). Where get this message set?

Thanks!
