Dash bar chart randomly disappear and only show up after refresh the page for couple times

Hi All,

Recently I have been facing the issue that my bar chart is not showing up until I refresh the page for couple times even though with data inside.

It shows like this most of the time,

after refreshing my page for a few time,

I am using hidden json to update my data, data itself is working for other callbacks, only fail with the bar chart.

Any ideas on this?

Thank you,


if you are asking help from community members, it would be helpful to share your dash app code (figure data for bar and callbacks), and also your dash version pip list | grep dash
