Unable to create new users with createAccount

We are working with Hypi, but getting an issue when we create users and create accounts.
User schema:

Query to create user:

We are getting the below errors if we are not sending token to create user:

The same issue is received with the create account mutation:

You have anonymous requests disabled in your app’s instance.

Anonymous requests must be enabled for this instance otherwise you cannot make any request without an authorisation token - including creating an account.

When you create a new app instance - i.e. when you create the domain, each one has their own setting. Enable this by opening your instance (click the domain name) and selecting the appropriate checkbox.
