Cant do migration laravel 8 - laravel

Question

I'm new to laravel. Help please.
Error in the console when trying to migrate:
Migrating: 2022_03_15_224441_add_permission_menu_table
Illuminate\Database\QueryException

I do not know what other details to describe to make it clearer what the problem is.
Please ask me if need what else.

Answer 1

<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class AddPermissionMenuTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('permission_menu', function (Blueprint $table) {
//
$table->bigInteger('permission_id')->unsigned();
Change integer to bigInteger on permission id

Answer 2

I decided so, for the permission_menus table I changed:
Schema::create('permission_menu', function (Blueprint $table) {
//
$table->integer('permission_id')->unsigned();
$table->foreign('permission_id')->references('id')->on('permissions')->onDelete('cascade');
$table->bigInteger('menu_id')->unsigned();
$table->foreign('menu_id')->references('id')->on('menus')->onDelete('cascade');
});
And for the menus table:
Schema::create('menus', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('title');
$table->string('path');
$table->integer('parent');
$table->string('type');
$table->integer('sort_order')->default(100);
$table->timestamps();
});
And everything worked. Thanks!
I also tried to do this for the menus table left:
$table->increments('id');
And for the permission_menu table:
$table->integer('menu_id')->unsigned();
and everything worked too. It turns out to be a mismatch of two fields of two connected tables.
