Schema::defaultStringLength(191);
in AppServiceProvider didn't work for me. What worked for was editing the database.php file in config folder. Just edit

'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',

'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
and it should work, although you will be unable to store extended multibyte characters like emoji.

// Go to your AppServiceProvider.php and update the boot() method with:

public function boot()

Inside config/database.php, replace this line for mysql

Copy Code
'engine' => null',
with

Copy Code
'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',
Instead of setting a limit on your string lenght.

According to the official Laravel 7.x documentation, you can solve this quite easily.

Update your /app/Providers/AppServiceProvider.php to contain:

public function boot()
{
    Schema::defaultStringLength(191);

Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes

// Solution 1
// In App/Providers/AppServiceProvider.php

use IlluminateSupportFacadesSchema;

public function boot()
{
    Schema::defaultStringLength(191);
}


// Solution 2
// In config/database.php
// For 'mysql' change

'mysql' => [
			// 'engine' => null,
            'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',
        ],
