How can I fix an infinite loop error on my cart page?

[Loulouis]

In the console I see that there is some kind of infinite loop on going. this is the error message : Uncaught TypeError: Cannot set properties of null (setting 'textContent')
at theme.min.js?v=91421670688963376431682442411:1:46755
(anonymous) @ theme.min.js?v=91421670688963376431682442411:1

Can anyone help me solve this ? I assume this has implications on the site speed.

This issue is due to javascript. You can fix it in theme files code
