React-diagrams: Uncaught TypeError: Cannot read property 'getLayers' of null

[novesia]

I am trying to migrate from v5 to v6 in a ES6 project, but I am having issues.
I've used the example code from https://projectstorm.gitbook.io/react-diagrams/getting-started/using-the-library.

Not sure what I am doing wrong, this should work for ES6 too, right?

index.js:24 Uncaught TypeError: Cannot read property 'getLayers' of null at Component.render (index.js:24) at finishClassComponent (react-dom.development.js:18450) at updateClassComponent (react-dom.development.js:18403) at beginWork$1 (react-dom.development.js:20160) at HTMLUnknownElement.callCallback (react-dom.development.js:337) at Object.invokeGuardedCallbackDev (react-dom.development.js:386) at invokeGuardedCallback (react-dom.development.js:441) at beginWork$$1 (react-dom.development.js:25737) at performUnitOfWork (react-dom.development.js:24661) at workLoopSync (react-dom.development.js:24637)

What is the value of the "engine" prop? Can you share the code please?

[novesia]

Oh man, I've found the issue after checking the engine prop (where model was null), the function where this.engine.setModel(this.model); happens was never called!

Thanks for your hint, Pierre!
