Hello Marcus,
So, the Waterfall sink is a custom plot that the Bokeh does
not provide by default. Because of this error and the warning,
I think Bokeh v0.12.6 and the current recent version has
significant API changes. I may need to look at it in detail.
Is it fine if I look at it in this weekend?
For now, it would suggest you downgrade the Bokeh to
version 0.12.6, and NodeJS version to v6.6? Those were the
versions I tested everything with. Let me know if that solves
the issue (temporarily). If you don't
Thanks.
