Hi, I know this is an old Issue and I don't know rather your problem had been solved or not.

These errors because of the setup tracker. In the documentation installation, it seems that there is lack of parameters needed for the database connection.

In the database connection on your config/database.php
try to add the username and password in the tracker database connection cause it seems there is a need in the connection.
Also it is preferable to use env as the tracker connection will update accord to the change of your enviroment

'connections' => [
      'mysql' => [
          'driver' => 'mysql',
          'url' => env('DATABASE_URL'),
          'host' => env('DB_HOST', '127.0.0.1'),
          'port' => env('DB_PORT', '3306'),
          'database' => env('DB_DATABASE', 'forge'),
          'username' => env('DB_USERNAME', 'forge'),
          'password' => env('DB_PASSWORD', ''),
          'unix_socket' => env('DB_SOCKET', ''),
          'charset' => 'utf8mb4',
          'collation' => 'utf8mb4_unicode_ci',
          'prefix' => '',
          'prefix_indexes' => true,
          'strict' => true,
          'engine' => null,
          'options' => extension_loaded('pdo_mysql') ? array_filter([
              PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
          ]) : [],
      ],
      ....
      'tracker' => [
          'driver'   => 'mysql',
          'host'     => env('DB_HOST', '127.0.0.1'),
          'database' => env('DB_DATABASE', 'forge'), //created different db since its mentioned
          'username' => env('DB_USERNAME', 'forge'),
          'password' => env('DB_PASSWORD', ''),
          'strict' => false,    // to avoid problems on some MySQL installs
      ],
],

After adding the tracker connection on config/database.php do remember to
php artisan config:cache

After that you could safely migrate the tracker table
php artisan migrate
