POST /{locale}/cart/add Required parameter missing or invalid: items

I am experiencing issues with your cart API endpoint “POST /{locale}/cart/add.js”. This request is returning the error “Required parameter missing or invalid: items”. However, I’ve been using this same cart implementation for several years, and the request hasn’t been modified. I double-checked with the documentation to ensure everything is correct, and it is. It seems like there might be something wrong on Shopify’s side specifically with this endpoint. Can anyone help?

Experiencing the same issue as well

Also experiencing this issue as of this morning.

Experiencing same issue without any changes made.

Same here, did someone solve it? It’s breaking my app.

Experiencing this issue since Saturday, and on a major promotional holiday weekend

Hey guys, for me the problem was that posthog override the fetch object.
