Hello All Hope you are well

I have one issue on my laravel database migration when I try to migrate my database table using this cmd command: PHP artisan migrate then below error is displayed

alter table users add unique users_email_unique(email)

do I have to change anything in my user's table file or is there any other setting

Thanks in advance
