Cannot read properties of null (reading 'nodeName')

[Y Y Wong]

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.

Hi,

What version of draw.io do you see in the help menu of the draw.io editor? If it's not 24.7.5, please go to clear.draw.io and try again.

Best,

David

I just check the draw.io version is v24.7.5.  And I just try on Chrome that I can open the same problem draw.io diagram without any issue now.  It seems the problem just disappeared.

Anyway, let me also try to use "clear.draw.io" to clear the cache now.

I just try a few times with different draw.io diagrams in my Confluence and they all work now.

I got this on both.  But it seems I have no such issue now and I just try on Chrome that I can open the same problem draw.io diagram for editing.
