Expected behavior Should not see javascript error in Ripple effect

Actual behavior seeing: ripple.js:115 Uncaught TypeError: Cannot read property 'offsetHeight' of null at n.value (ripple.js:115) at HTMLAnchorElement.e (event-handler.js:102) value @ ripple.js:115 e @ event-handler.js:102 navigation.js:71

Hi. Could you please provide a snippet with this error? It would help a lot. Thanks.

I recently experienced this same thing using the latest version of MDB5 (3.9.0) with the same stack trace. I've created a snippet where I ran into this that you should be able to use to duplicate.

Just click any of the menu links and you should see the console error. I am using Microsoft Edge but was able to duplicate in Google Chrome as well (running Windows 10).

It looks like it's failing on the Ripple class itself where the element is not defined (and therefore the offsetHeight is not defined):screenshot of bug

Let me know if I can be of more assistance in this regard as well, happy to provide more screenshots or information if needed.

I should note that the ripple seems to still work, it just creates a console error.

Thanks a lot for this snippet. We will take a closer look at this case. It seems weird because in this snippet everything works fine without errors

Keep coding,

Thanks Dawid!

I wonder if it's something with the slim side-nav specifically? Just a thought as that's really the only thing different. You're correct that this one appears to be fine. In my snippet I had not implemented a button to change to the slim mode, but notice in the code I set the data attribute to indicate it as slim.

It can be related to slim option. However, my quick check, which included removing slim options, didn't change anything. The error still occurs. We will investigate this. And thanks for help :)
