?add-to-cart= errors in Google Webmaster Tools with Woocommerce

I'm getting 100K + errors in GWT with ?add-to-cart= urls.

I'm using Woocommerce.

These errors occur everywhere you find a buy button.

url.com/page/68/?add-to-cart=123456
url.com/product-category/ABC/?add-to-cart=123456
url.com/product/XYZ/?add-to-cart=123456

They show up under "indexing"

Alternate page with correct canonical tag
Page with redirection
Crawled - not currently indexed

Is this something I need to fix for optimal ranking?

They are adding these parameters to results themselves.

Because they are part of product search.

It's common with Woo. GSC reports these because they're param URLs, but if canonicals point to main product pages and they’re not indexed — you're good.

Just as explained above, they're pretty normal to have as part of the website,
SEO-wise, you should block them via robots.txt to save crawl budget and avoid possible can, they're not meant to be crawled/indexed
