I'm new to Spartacus. When I try to add a product to the cart. I'm getting the following message. enter image description here The error occurs in the anonymous user and Logged in User.
I have tried what in the Spartacus documentation has ben written. But I haven't been able to fix it. I also tried to give all authentication to a user in the backoffice. But didn't help.
It's hard to say without seeing the error message from OCC call for adding to cart (you can check it e.g. by opening of Chrome DevTools -> Network tab).
From top of my head: Currently, for B2B storefront, you need to use the B2B variations of the OCC endpoints - see defaultB2bOccConfig. Perhaps you're missing the B2B-flavoured configuration of OCC endpoints in your Spartacus app. Please try providing in your app module (or in your SpartacusConfigurationModule):
import { defaultB2bOccConfig } from "@spartacus/setup";
/* ... */
providers: [
/* ... */,
provideConfig(defaultB2bOccConfig)
]
