Links are not crawlable

[P2]

Hello There,

A Web.dev  test of www.progetto-due.com shows this error in the SEO section: Links are not crawlable. 

The error is located in the hamburger menu:

<a href="" class="site-nav__link site-nav__link--icon js-drawer-open-button-left" aria-controls="NavDrawer" aria-label="Menu" aria-expanded="false">

What can I do to fix It?

Thanks!

Hello did you fixed it? 

Because I have the same issue

body.gradient > div#tab-box-front-0 > div.tab-box-content > a.coupon-tab-close

<a href="javascript&colon;void(0);" class="coupon-tab-close">
