bug: client.create_token returning a token but silently failing to create a user

Comienza rastreando los puntos de entrada del cliente Ruby mencionados en el informe: client.create_token y channel.add_members; después, reproduce la secuencia con el ejemplo de Ruby proporcionado. Compara la respuesta del token con el comportamiento posterior de actualización del canal y revisa las pruebas existentes del cliente o el manejo de solicitudes; se considera completado cuando el flujo de creación de usuarios y su comportamiento ante errores coinciden con el contrato documentado de la API.

Describe the bug

I've got code which, on visiting the "messenger" page for the first time, attempts to create a user and add them to a default list of channels.
I create a token using client.create_token, then attempt to add the user to a few channels.

However, I'm getting the exception

StreamChat::StreamAPIException (StreamChat error code 4: UpdateChannel failed with error: "The following users are involved in channel update operation, but don't exist: [94461a35e0a73734438dba5ba10bbb74]. Please create the user objects before setting up the channel.")

client.create_token returns a 200 success and also returns a token.
The only exception I get is when I consequently try to add the user, using my manually generated user_id, to channels.

This was working yesterday - my code around user creation doesn't seem to have changed.

To Reproduce

1. Create a user using client.create_token(id) (I'm using id = SecureRandom.hex(16))
2. Attempt to add user using channel.add_members([id])

Expected behavior

The create_token endpoint should:

1. create a user if params are valid (which in this case they are); AND
2. return an error if params are invalid OR the server is experience issues, so error handling can be handled

My StreamChatClient class:

    members.map{ |member| member["user_id"] }.include?(user_id)
  end

  def self.get_channel(type:, channel_id:)
    client.channel(type, channel_id: channel_id)
  end

  def self.create_stream_user(id:)
    client.create_token(id)
