Error : Setting up an Admin Backend - isInternational

[Lainocs]

Hello,
I was reading the fast track, and discovered what I think is an error.
In chapter Setting up an Admin Backend, after implementing the __toString method, I tried to create a Conference but was met with the following message :

The method "isInternational" in class "App\Entity\Conference" requires 0 arguments, but should accept only 1..

I made sure to follow each previous step thoroughly, so unless something slipped past me, there may be an error somewhere.
I have not found a solution yet, but I'll make sure to share it here if I do.

Cheers 😄

I tried adding 2 methods getTest and setTest in my Conference entity like so:

public function setTest(bool $test)
{
    $this->isInternational = $test;
    return $this;
}

public function getTest(): ?bool
{
    return $this->isInternational;
}

And I set the boolean field in my CRUD to use these test methods:

BooleanField::new('test'),

And it works now!
I think the problem might be coming from the property being called isInternational but I am fairly inexperienced with Symfony and I afraid I wouldn't know how to fix it.
Hope this will help anyways 🏃🏼

I have encountered the same problem.
Renaming isInternational() to getIsInternational() and setInternational() to setIsInternational() for Conference did solve it.
This is just a dirty quick fix and i hope someone can provide a proper solution.
