Then you should check if they are spawned I think.

PHP Code:

public OnPlayerSpawn(playerid)
{
    if(GetPVarInt(playerid, "is_connected")==0) SetPVarInt(playerid, "is_connected", 1); // set the pvar to 1 for the check later
    return 1;
}

IsPlayerConnectedEx(playerid)
{
    if (IsPlayerConnected(playerid)&&GetPVarInt(playerid, "is_connected")==1&&playerid!=INVALID_PLAYER_ID) return 1;
    return 0;
}

CMD:gotoplayer(playerid, params[])
{
    new ID, string[128];

    if(sscanf(params, "u", ID))
        return errormessage(playerid,"/gotoplayer -ID-");

    if(!IsPlayerConnectedEx(ID))
        return errormessage(playerid,"No players found");

    new Float: Pos[3];
    GetPlayerPos(ID, Pos[0], Pos[1], Pos[2]);
    SetPlayerPos(playerid, Pos[0] + 2, Pos[1], Pos[2]);
    
    SendClientMessage(playerid, COLOR_ADMIN, "Teleported");
    return 1;
}
