Plotly Cloud Error NoneType Object

Hi, sorry if I made a mistake since I am new to this forum.

I am working on a project, and I am testing the Plotly Cloud services. My app is very simple at the moment.

However, selecting Plotly Cloud button at the debug option always causes error: cannot create weak reference to ‘NoneType’ object.

All callbacks are not None.

Please help. Thank you very much.

Hey @caljoseph, it is pretty difficult to help you with the information provided.

If you supplied some code, users could try to help you based on that.

Hi,

I tried multiple things. Firsly, I created a fresh new project with the minimal dash app. I used python3.14 on Ubuntu. Unfortunately, it does not work.

Everything works fine when I uploaded the files directly to plotly cloud, instead of the button on the local debug.

Hi @caljoseph we believe this is an issue with the package and are working on resolving it. You can track progress here: [BUG] Publish to Cloud fails with `error: cannot create weak reference to ‘NoneType’ object` · Issue #3662 · plotly/dash · GitHub
