Shopify connected to search google console alternative canonical tagas and 404 error.

[SofiaN1]

Hi,

I have added my shopify store to search google console. It says its been verified and found 5 pages. However, 238 pages could not be indexed. It says its due to "Alternative canonical tags". Ive understood that this means there are double canonical tags. When i search for my site on google using site: my pages are coming up but when i click on them, it shows a 404 error.

How do i fix this? Can someone help?
