I don't see the first function node when I import Dave's flow. Where did it come from??
@dceejay When I first import the flow, the function node is fine, but if I open it and close it without making a change, the red triangle shows up. the cause it the first if statement
if (bytes[0]==01) {
If I change the 01
to 1
then the configuration error goes away, changing it back to 01
and the issue pops up again.
