Y values not showing when deploy to Heroku

Hi all might someone know why my charts are not rendering(y values are missing) when deployed to Heroku but works fine in localhost. I have the same environmental dependencies in both setups.

This has been working fine all the years till I noticed it was broken a last month. Attached is a localhost snippet. When you compare with the live one, the y axis begin from 1,2,3, … and keeps increasing. Some charts do not even show totally.

That’s really weird. I wonder if it’s a Heroku issue. Do you know if the Dash or Plotly versions installed on Heroku servers in your project have changed?

You can always try to deploy your Dash app to the new Plotly Cloud and see if this issue disappears.
