Laravel : Syntax error or access violation: 1055 Error

Short answer

In config\database.php --> "mysql" array

Set 'strict' => false to disable all.

.... or

You can leave 'strict' => true and add modes to "mysql" option in

'mysql' => [
       ...
       ....
       'strict' => true,
       'modes' => [
            //'ONLY_FULL_GROUP_BY', // Disable this to allow grouping by one column
            'STRICT_TRANS_TABLES',
            'NO_ZERO_IN_DATE',
            'NO_ZERO_DATE',
            'ERROR_FOR_DIVISION_BY_ZERO',
            'NO_AUTO_CREATE_USER',
            'NO_ENGINE_SUBSTITUTION'
        ],
 ]

Detailed answer

You may not need to disable all strict options ... Kindly have a look on this answer about this issue.

This is probably a SQL_MODE problem. In your config/database.php, in the connection, change

strict => false

As in

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', 'localhost'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => false,
    'engine' => null,
],
