Recently, we got the "Cannot read properties of null (reading 'nodeName')" error when opening an existing draw.io diagram within Confluence (Cloud). If we download the .drawio file to local and use "app.diagrams.net" to open it, it successes without any error.
May I know if anyone hit the same issue and how we can fix this.
[Follow-up]
We just find that the problem will happen if we create a second page in Draw.io and assign it as the "background" of the frist page. After publishing the diagram and re-open it in Conflucence editor, the problem will happen.
However, if we download the .drawio file and open it in draw.io "app.diagrams.net", it can be open without any issue.
Hope that Confluence (Cloud) team can find a solution on this.
