How to fix "Operation FindFriends (222) not called because client is not connected or not ready yet, client state: PeerCreated." in Photon

Question

So here I am trying to add a Player as a friend to myself. I am following a tutorial for the same

So I am using the PlayFab to update the friend List. When the update is successful onFriendListSuccess() function is executed as given below.

private void onFriendListSuccess(GetFriendsListResult result)

  {

    friends = result.Friends;

    onFriendListUpdated?.Invoke(result.Friends);

   }

In the above function as seen onFriendListUpdated event is invoked.In the listener basically this is the code:

private void HandleFriendsUpdated(List<PlayFabFriendInfo> friends)

  {

    if (friends.Count !=0)

    {

      string[] friendDisplayNames = friends.Select(f => f.TitleDisplayName).ToArray();

      PhotonNetwork.FindFriends(friendDisplayNames)//-------------PROBLEM------------------

    }

    else

     {

      List<PhotonFriendInfo> friendList = new List<PhotonFriendInfo>();

      onDisplayFriends?.Invoke(friendList);

     }

But I am getting the following error as given here:

Operation FindFriends (222) not called because client is not connected or not ready yet, client state: PeerCreated
