Hi Emil. I tried to use your code in a multiple page app but didn’t have any success. I would really appreciate if you can help me.

I use the same design for the web as this Dash App Gallery repo. Then I create a new page with the exact same code as yours. No matter what I always get the error below

Cannot read properties of undefined (reading 'src')

(This error originated from the built-in JavaScript code that runs Dash apps. Click to see the full stack trace or open your browser's console.)
TypeError: Cannot read properties of undefined (reading 'src')
