Could you double-check the existing configuration in the .env file to ensure it reflects the latest updates? Auth0 has changed some property names in the most recent version.

In my case:

• AUTH0_BASE_URL should be APP_BASE_URL

• AUTH0_ISSUER_BASE_URL should be AUTH0_DOMAIN

You can refer to the latest documentation here for more details.

The complete list of updated environment variable names is as follows:

AUTH0_SECRET='use [openssl rand -hex 32] to generate a 32 bytes value'
APP_BASE_URL='http://localhost:3000'
AUTH0_DOMAIN='https://xxx.auth0.com'
AUTH0_CLIENT_ID='{yourClientId}'
AUTH0_CLIENT_SECRET='{yourClientSecret}'
