Need help with getting name from config!

Hello there,

Im creating my own plugin where I have some teams.
When a player joins a team. The players name will be stored in a config.yml.
But now when i reload or join the server again the player is no longer in a team so I though I create a check when a player's name is in the team/config. It will automatically rejoin the team again.

Only when I create the check. It gives me a nullpointer no matter what I check from the config.
Can someone help me?

The piece of code is:

Code:

    public static String getPartyOwnedByPlayer(Player player) {
        if(CustomConfig.get().getString("Teams:") == null) {
                CustomConfig.get().createSection("Teams:");
                CustomConfig.save();
                player.sendMessage(ChatColor.RED +"test");
            } else {
                String playerName=player.getName().toString();
               

               
               
                    if (CustomConfig.get().getString("Teams:.TeamMB.Players.").contains(playerName) && CustomConfig.get().getString("Teams:.TeamMB.Players.") != null) {
                        Teams.addToTeam(TeamType.MB, player);
                        player.sendMessage("Test");
                        return playerName;
                    } else {

                        player.sendMessage(ChatColor.RED + "Je zit niet in een team!");
                        return playerName;
                    }
                   
                   

            }
        return null;
       
    }
}

The error i get is:

 

@tinusium Your config path includes:

Code:

Team:.*

You probably mean to use:

Code:

Team.*
