Flow.fill isn't working

[bdidds2]

I have a sankey chart with 21 nodes, and I'm trying to fill the flows one of three colors, but flow.fill isn't working. Is there more documentation on how it works?

+1 the entire package is not working and garbage. works only with example data, that's it. used my data in exact same data format but doesn't work.

@dennisbenner please make a reprex of the garbage
