AADB2C90010: The request does not contain a scope parameter

Question

I have an azure static web app with B2C authentication setup as a custom provider as shown below.

However, when I try to sign in, it returns error: AADB2C90010: The request does not contain a scope parameter.
Watching network activities, the regular OIDC/OAuth redirect dances do happen but scope is in fact missing. Shouldn't it have applied some default OIDC scopes at least? I even added openid, profile and offline_acces scopes to the provider definition. What am I missing?

Turns out it is a simple typo....scopes...🤦‍♂️

"login": {
            "nameClaimType": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name",
            "scopes": ["openid", "profile", "offline_access"],
            "loginParameterNames": []
          }

I will leave it here in case for someone like me :-)
