Codesandbox bpmn-js-properties-panel-extension broken

Hello everyone,

while trying to provide a codesandbox for this thread, I found a bug in the template for bpmn-js-examples/properties-panel-extension at master · bpmn-io/bpmn-js-examples · GitHub in bpmn-js-example-properties-panel-extension - CodeSandbox.

When opening the template, I am greeted by an error message about a misformatted json. After I corrected that error, the next one is " TypeError Cannot read property ‘appendChild’ of null". I do not know how to fix this second error. Can anyone help me out?

If this is the wrong place to report this bug, I would be glad to bring it up somewhere else, I just don’t know where.

I think the examples are not ready to be imported into CodeSandbox. Most examples use their own build infrastructure that might not work with the CodeSandbox setup.

You can use this one instead: bpmn-js-examples properties panel extension - CodeSandbox

Thanks for clearing that up, then I’ll simply use the one you provided.
