kcFakeLogin stuck on redirecting

[MarkLyck]

When trying to login with kcFakeLogin, cypress just gets infinitely stuck on page loading.

my users/user.json fixture:

{
  "username": "mark@*****.com",
  "password": "*****",
  "fakeLogin": {
    "access_token": "*****",
    "refreshToken": "*****",
    "id_token": "*****",
    "account": {}
  }
}

I've tripple checked the tokens and info above are correct (copied from a real login).

my test:

describe('Keycloak', () => {
  it('Keycloak loads', () => {
    cy.kcFakeLogin('user');
  });
});

initConfig:

{
        flow: 'implicit',
        onLoad: 'check-sso',
        checkLoginIframe: false,
}

(I have tried replacing this with the one from your docs, but that didn't work either).

cypress.json

{
  "baseUrl": "http://localhost:3000",
  "env": {
    "auth_base_url": "https://sso.****.com/auth",
    "auth_realm": "****",
    "auth_client_id": "react-admin",
    "auth_client_secret": "*****"
  }
}

my normal keycloak.json looks like this:

{
  "auth-server-url": "https://sso.*****.com/auth",
  "confidential-port": 0,
  "credentials": { "secret": "*****" },
  "realm": "rogers",
  "resource": "react-admin",
  "ssl-required": "external"
}

I'm not sure if there's anything special here that this npm module isn't built to handle?

Visiting localhost:3000 of course works just fine in the browser.

I've been trying to get this working for 5 hours today with no luck.

Interesting... I have a similar issue:
I am using Vue with VueX and vuex-oidc (an oidc-client implementation for vue+vuex). I have a .env.local file with auth-provider A:

VUE_APP_AUTH_PROVIDER_URL="https://auth.providerA.com/auth/realms/my-realm"
VUE_APP_AUTH_CLIENT_ID="my-client"

and my cypress.json has configured provider B:

{
  ...
  "env": {
    "auth_base_url": "https://auth.providerB.com/auth",
    "auth_realm": "my-realm",
    "auth_client_id": "my-client"
  }
  ...
}

When I use kcFakeLogin("user") somehow cypress tries to open a frame to https://auth.providerA.com - which makes me wonder, since my cypress.json is using providerB ... Both are configured and work in dev mode, but cypress somehow doesn't know which one to use...

Update

I figured out how to fix my chrome-error, redirects-error, CORS-error issues.
Maybe this can help.
