Php artisan migrate gives different result with the same code - php

Question

pic1
pic2
Pic 2 is the usual laravel migration tables that i created. Pic 1 is the laravel migration tables that i newly created. They have the same code with same foreign key only with different attributes name. Why is pic 1 only have varchar(191) instead of varchar(255), and the foreign key doesnt apply from migrations anymore? Before pic 1, i did ran some stuff on terminal for deployment purpose like npm build. Is the terminal the cause of this?
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
return new class extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('calibrations', function (Blueprint $table) {
$table->id();
$table->string('Identification_No');
$table->foreign('Identification_No')->references('Identification_No')->on('fieldequips');
$table->string('Calibration_point');
$table->date('Expired_Date');
$table->date('Calibration_Date');
$table->date('Next_Due_Date');
$table->string('Correction_factor');
$table->string('Validated_by');
$table->date('Validated_Date');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('calibrations');
}
};

In app/Providers/AppServiceProvider.php you should change Schema::defaultStringLength(191) to Schema::defaultStringLength(255), I guess
