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.
