• Laravel Version: 5.8.21
• PHP Version: 7.3.4
• Database Driver & Version: mysql 8.0.16
• PHPUnit: 8.2.1

likely a duplicate of: https://github.com/laravel/framework/issues/26874, but it was close 6 months ago. but there have been a few comments in the last month or so. perhaps others, like me are getting an issue still.

Description:

i'm getting this error (after adding https://github.com/sebastiaanluca/laravel-auto-morph-map via composer). when i run phpunit i get a few fatal errors. not sure how/why the package would have messed it up. so any help would be great!

PHP Fatal error:  Cannot declare class App\Middleware\FixedStartSession, because the name is already in use in /app/app/Http/Middleware/FixedStartSession.php on line 21

Have you tried composer dump-autoload?

Have you tried composer dump-autoload?

yes. i read that from some other thread/issue whilst in this google rabbit hole. it still doesn't work.

Have you tried removing the package?

Unfortunately this GitHub area is not a support area for general application issues. This is only for issues/bugs with the framework code itself.

I will be closing your ticket here. Instead please try asking your question on one of the many great community support areas that will likely give you a better answer more quickly:

• Laravel Slack (https://larachat.co/)
• Laravel.io Forum (https://laravel.io/forum)
• Laracasts Forum (https://laracasts.com/discuss)
• StackOverflow (http://stackoverflow.com/questions/tagged/laravel)

If you feel I've closed this issue in error, please provide more information about how this is a framework issue, and I'll reopen the ticket.

Thanks in advance.

For me it turned out to be access rights. This might be an issue for vm/container environments.
