Reported the same thing in another thread, facing the same issue, did try the
“http://127.0.0.1:9292/cart/32660962476113:1?storefront=true” to test the end point to add a product, that also did not work.
broken for me in CLI at version:
/cli/3.90.0 win32-x64 node-v25.2.1
This is the response I get from the browser console
