I am trying to create a temporary channel what is working with "Slash" commands. I am almost there but I am getting an error when creating a second channel because the "voiceStateUpdate" is getting called twice.

else if (commandName === "createchannel") {
   var channelName = options.getString("channelname");
   var rolesThatCanJoin = options.getRole("roles");
   var state = options.getString("state");
   var channel = interection.guild.channels.create(channelName, {
        type: "GUILD_VOICE"
        }).then((channel) => { 
        channel.setParent("670691620844470320")
        createdChannelID = channel.id;

        interection.reply({
          content: `**Channel named:** ${channelName}\n**Role that can join:** ${rolesThatCanJoin}\n**State:** ${state}`,
                ephemeral: true,
                })

        client.on('voiceStateUpdate', (oldState, newState) => {
            var newChannelID = newState.channelId;
                
            if (newChannelID === createdChannelID) {
              console.log("User has joined voice channel with id " + newChannelID);
            } 
            else {
               console.log("User has left");
               channel.delete()
            }
         });
      });
    }

Console:

User has joined voice channel with id 936252040865284156
User has left
User has joined voice channel with id 936252068568641576
User has joined voice channel with id 936252068568641576
User has left
User has left

Error:
