queue.size() is not a function

Using this code here (the player passed in is valid):

 const tracks = player.queue;
      //if there are no other tracks, information
      if (!tracks.size())
        return message.reply({embeds : [new MessageEmbed()
          .setAuthor(`Queue for ${message.guild.name}  -  [ ${player.queue.size()} Tracks ]`, message.guild.iconURL({
            dynamic: true
          }))
          .setColor(es.color).addField(eval(client.la[ls]["cmds"]["music"]["queue"]["variablex_1"]), eval(client.la[ls]["cmds"]["music"]["queue"]["variable1"]))
          .setDescription(eval(client.la[ls]["cmds"]["music"]["queue"]["variable2"]))
        ]}).then(async (msg) => {
          setTimeout(()=>{try { 
            msg.delete().catch(() => null);
          } catch {} 
          }, 5000)
        })

 const tracks = player.queue;
      //if there are no other tracks, information
      if (!tracks.size())
        return message.reply({embeds : [new MessageEmbed()
          .setAuthor(`Queue for ${message.guild.name}  -  [ ${player.queue.size()} Tracks ]`, message.guild.iconURL({
            dynamic: true
          }))
          .setColor(es.color).addField(eval(client.la[ls]["cmds"]["music"]["queue"]["variablex_1"]), eval(client.la[ls]["cmds"]["music"]["queue"]["variable1"]))
          .setDescription(eval(client.la[ls]["cmds"]["music"]["queue"]["variable2"]))
        ]}).then(async (msg) => {
          setTimeout(()=>{try { 
            msg.delete().catch(() => null);
          } catch {} 
          }, 5000)
        })
