CODE EXAMPLE FOR PHP

php artisan vendor:publish --provider="SpatieActivitylogActivitylogServiceProvider" --tag="activitylog-migrations"

Had the same issue when I ran
php artisan vendor:publish --provider="SpatieActivitylogActivitylogServiceProvider" --tag="activitylog-migrations"
php artisan vendor:publish --provider="SpatieActivitylogActivitylogServiceProvider" --tag="activitylog-config"

I got rid of it by running:
php artisan vendor:publish --provider="SpatieActivitylogActivitylogServiceProvider" --tag="migrations"
php artisan vendor:publish --provider="SpatieActivitylogActivitylogServiceProvider" --tag="config"
