Argument of type 'string' is not assignable to parameter of type '"api"'

After migrating to the new version an error appeared and I did not understand what happened. Could someone help me?

protected async authenticate(auth: HttpContextContract['auth'], guards: string[]) {
    for (let guard of guards) {
      if (await auth.use(guard).check()) {
        /**
         * Instruct auth to use the given guard as the default guard for
         * the rest of the request, since the user authenticated
         * succeeded here
         */
        auth.defaultGuard = guard
        return true
      }
    }

    /**
     * Unable to authenticate using any guard
     */
    throw new AuthenticationException(
      'Unauthorized access',
      'E_UNAUTHORIZED_ACCESS',
      this.redirectTo
    )
  }

Argument of type 'string' is not assignable to parameter of type '"api"'.
