TypeError: nodes[0] is undefined - custom priority parameter

[Mihailoff]

I'm using a custom priority parameter and getting the following error TypeError: nodes[0] is undefined

chartjs-chart-sankey/src/layout.js

Line 215 in 9dbd19f

nextYStart = nodes[0].to.filter(to => to.node.x > x + 1).reduce((acc, cur) => acc + cur.flow, 0) || 0;

nodes[0] assumes that there is always at least one element and this is not true in my case.

chartjs-chart-sankey@0.11.0
chart.js@3.8.2

Don't know if this is related or not. In my data set, if I filter items with flow > 1 the error goes away.

If you can, please provide a codepen or equivalent that reproduces the issue.
