Hi Serena,
I did some more testing on this and for me the error message goes away when I select the variable in the label field.
I can publish the flow and it is working as intended, but when I edit the flow again the error message is there.
This is probably something that needs to be reported to support so they can fix it.

Jan Heinonen I have initialised the variable labelSend. If I print the variable Flow.labelSend in the communicate block, as the FIRST block of the flow, it prints it correctly with correct initial value.

Hi Serena,
You need to declare the variable somewhere in the flow before you can use it, or you'll get that error message.
