Multipage, mutliple callbacks are not working

Dash Python
1

Dear Team,

I have created a multipage app with each page having multiple graphs(multiple callbacks). It is working for some (old) callbacks. However, the dash app layout is not rendering any page if I add new callbacks. No errors are displayed too in the console or terminal.

I have tried different options:

  1. app.run_server(debug=True) → page not even loading
  2. app.run_server(debug=False) ->page loading but no graph outputs on page
  3. reduced number of callbacks from 15 to 10 (I have combined multiple callbacks)

Note: All pages are working independently. (they are not working after adding together and no errors in console)
Link for my dashboard: https://greektragedy.herokuapp.com/
Link for the code: GitHub - VIJAYAYERUVA/greektragedy: This repo is for 'Greek Tragedy' visualization.

Currently, I don’t have a specific ‘code’ that is throwing errors.

Is there a limit on the number of callbacks on each page?

Hello @vijaya

No there isn’t any limit on the number of callbacks. If there are no errors showing up on the terminal, you can try looking on the web console of your browser.

@atharvakatre, thank you for your response.
I was so dumb that I forgot to check the web console. It helped me.
The issue was I am using the same layout ‘id’ on different pages. I thought that I could use the same ‘id’ on different pages.
