Trouble with auto load

[olacombe]

Hi there

I have a behaviour I don't undertsand.

When I add :
#import sanctum.graphql

php artisan lighthouse:ide-helper tell me :

Nuwave\Lighthouse\Exceptions\DefinitionException 
**Duplicate definition login found when merging.**

I don't understand why because I already make a project with lighthouse and lighthouse several months ago, and I didn't meet this trouble.

Is there something change rescently?
This problem can come from Laravel last release with an "Autoloader"?

Thanks for your help :)
