Large error 5.6 "Undefined property"

I'm trying to list an association table, in my case it's the class table, which associates officials (teachers) and students.

I gave a good researched before posting this question but I could not solve the problem.

Role model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Illuminate\Database\Eloquent\Relations\Pivot;


class Funcionario extends Authenticatable
#class Funcionario extends Model

{
    use Notifiable;

    protected $fillable = [
    'login','password','nome', 'sobrenome', 'nome_completo','rg','cpf','email',
    'cargo', 'data_registro','data_nascimento', 'nivel_acesso', 'sexo',
    'telefone','telefone2',
    'cidade','endereco','bairro','numero','cep','estado_id','escola_id',    
    ];

    protected $hidden = [
        'password','remember_token'
    ];

    public function estado()
    {        
        return $this->belongsTo('App\Models\Estado');
    }

    public function escola()
    {    
        return $this->belongsTo('App\Models\Escola'); 
    }

    public function alunos()
    {    
        return $this->belongsToMany('App\Models\Aluno','turmas','funcionario_id','aluno_id')
        ->withPivot('serie','nome','nivel','professor','periodo','id'); 
    }

    
}

student model

<?php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Aluno extends Authenticatable{
    use Notifiable;
    protected $fillable = [
    'login','password','nivel_acesso','nome','sobrenome','nome_completo','certidao_nascimento',
    'data_nascimento','data_matricula','naturalidade','ra','rm','raca','cor','rg','cpf',
    'email','sexo',

    'telefone','telefone2',
    
    'cidade','endereco','bairro','numero', 'cep',

    'estado_id','escola_id',    
    ];

    protected $hidden = ['password','remember_token'];

    public function responsaveis()
    {        
        return $this->belongsToMany('App\Models\Responsavel');
    }

    public function escola()
    {        
        return $this->belongsTo('App\Models\Escola');
    }

    public function estado()
    {        
        return $this->belongsTo('App\Models\Estado');
    }

    public function necessidades()
    {        
        return $this->hasMany('App\Models\Necessidade');
    }

    public function funcionarios()
    {        
        return $this->BelongsToMany('App\Models\Funcionario','turmas','aluno_id','funcionario_id')
        ->withPivot('serie','nome','professor','periodo','nivel');
    }
}
