@steveblue any chance you merge this quickly and create a 9.0.2 release?

Hi @steveblue @fhayd
any updates on this?

Hi @steveblue @fhayd we would like to update to 9.x, any updates for this issue?

I quickly solved the issue by adding these:
in the HTML:

 <ngx-graph
        *ngIf="treeNodes?.length >= 0 && treeLinks?.length >= 0"

and in typescript file

  treeNodes: Array<RecipeStepNode> = [];
  treeLinks: Array<Edge> = [];

and make sure to initialize them as well in the onInit with empty values before add the actual data.

  this.treeNodes = [];
  this.treeLinks = [];

  this.treeNodes = [];
  this.treeLinks = [];

This doesn't solve our problem, as we want to display single nodes without any links :(
We'd need the official fix released asap, it is a showstopper for us.

It shows the node without links, but the error will still appear in the browser console. But this is jus a workaround to make it work smoothly.

I ended up with this solution: if links array is empty then I push a link pointing to the single node itself, and setting the width to zero.

Can u share the code itself?

you could also simply add a patch:

@swimlane+ngx-graph+10.0.0.patch

add patch-package to package.json and add patch-package to postinstall

@MarkColeman1 can you please merge this PR?

This issue should be addressed in 12.0.0, which also includes a rewrite to make ngx-graph standalone and use signals.
