Javascript Error (Illegal Invocation & Cannot Read Properties of Undefined)

[g3xfitness]

Hey there.

I have my site connected to Microsoft Clarity for analytics. 

And today on 02/29/24, looking at the recordings; it showed me I have some Javascript errors on my website.

Illegal Invocation & Cannot Read Properties of Undefined (reading 'dataset') 

Now, when i see the recordings (it was only 4 recordings that it happened on)

the users were on a linux device apparently. Mobile & Desktop. I have attached the screenshots.

And also looking at the recording, it seems it's coming from the t-shirt product.

Seems the user came from FB directly to the t-shirt product, never clicked or scrolled anything on the page

But somehow it showed me that error.

Unless, it was on the user's end directly. 

i added the link to my website below & I also added the link of the t-shirt product as well. 

I am honestly not a coder or developer nor do I have a developer or anything.

So, not sure how major that issue can be or if there's a way to fix it.

Would appreciate the help..

I'm having exactly the same issues for multiple of our clients. Can't figure out what to fix unfortunately..
