Get mystic error when rendering with layered algorithm

[geohuz]

I'm using elkjs with react to write an App in which user can add nodes interactively, the app crash occasionally when adding about more than 50 nodes. The ELK version: elkjs": "^0.8.2", the config option:

"elk.algorithm": 'layered',
      "layering.strategy": "BF_MODEL_ORDER",
      "elk.direction": direction,
      "nodePlacement.strategy": "BRANDES_KOEPF",  / 
      "spacing.edgeNodeBetweenLayers": 15,
      'elk.layered.nodePlacement.bk.fixedAlignment': 'BALANCED',  
      'elk.layered.crossingMinimization.forceNodeModelOrder': 'false',  
      'considerModelOrder.strategy': 'NODES_AND_EDGES'

The error message:

elk-worker.min.js:3668 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'he')

Hi, did you manage to find a solution?

Same error !

@RemiKalbe How do you use elkjs? Do you use it as specified in the readme or differently.

@RemiKalbe @hovik-geodakyan I had a really similar error that was caused by the nodes I passed in not having a width/height. Adding a fallback width/height fixed the issue.
