Getting cart not found error even when the cart is present - spartacus-storefront

Question

We are using Spartacus 1.4.2 and in production environment we are getting a "Cart not found." message frequently.
This happens for both logged in and guest customers.
We found a github link which is similar to our problem
https://github.com/SAP/spartacus/issues/4622
We would like to know what was the fix done for this.
This can appear on any page while browsing.
We believe it has something to do with the MultiCartService.
Following are the requests for which the error occured.
