Hi @bnovc, can you be more specific about the code you are running to see this error? e.g. a simple self-contained example that illustrates the problem? Thanks
@ricklupton I have been wrestling with similar issues for the past day and a half. Here is the simple setup:
const sankeydata = {
nodes: [
{ name: "Barry" },
{ name: "Frodo" },
{ name: "Elvis" },
{ name: "Sarah" },
{ name: "Alice" },
],
links: [
{ source: 0, target: 2, value: 2 },
{ source: 1, target: 2, value: 2 },
{ source: 1, target: 3, value: 2 },
{ source: 0, target: 4, value: 2 },
{ source: 2, target: 3, value: 2 },
{ source: 2, target: 4, value: 2 },
{ source: 3, target: 4, value: 4 },
],
};
var layout = sankey()
.extent([[20, 10], [width - 20, height - 10]]);
var diagram = sankeyDiagram()
svg.datum(layout(sankeydata)).call(diagram)
Here is the error that I get:
ndle.js:8724 Uncaught TypeError: Cannot read properties of undefined (reading 'length')

I have simple code setup with webpack dev server, nothing too fancy. But I can't seem to figure out why is this happening. So far I have tried with different data sets but nothing works.
Using the basic example on https://ricklupton.github.io/d3-sankey-diagram/, I get the following:
-sankey-diagram.umd.js:20584 Uncaught TypeError: Cannot read properties of undefined (reading 'length') at titlePosition (d3-sankey-diagram.umd.js:20584:1) at HTMLUnknownElement.eval (d3-sankey-diagram.umd.js:20467:1) at Selection.eval [as each] (each.js:5:1) at sankeyNode (d3-sankey-diagram.umd.js:20458:1) at Selection.eval [as call] (call.js:4:1) at updateNodes (d3-sankey-diagram.umd.js:20744:1) at HTMLDivElement.eval (d3-sankey-diagram.umd.js:20711:1) at Wn.each (d3.min.js:2:25626) at exports (d3-sankey-diagram.umd.js:20674:1) at Wn.call (d3.min.js:2:25196) t
