CreateUser(Email, Password) 500 internal error

[Stanmozolevskiy]

I am trying to create a new user using .net 5 project.

In order to communicate with firebase you need to create a client, which I am able to do with no problem and I am able to Push and Pull data to the database. However when I am trying to create a new user using client.CreateUser(Email, Password); I am getting the following error.

I did activate Email/Password auth method in the Firebase.
The Error I am getting:
