Minimal steps to reproduce

Followed the registration steps for both the apps https://github.com/Azure-Samples/active-directory-b2c-javascript-nodejs-webapi and https://github.com/Azure-Samples/ms-identity-b2c-javascript-spa#register-the-client-app-javascript-spa.

When trying to hit sign in post registration shows me an error
