VS Code Symfony undefined method when exists

[BernardA]

Describe the bug Shows error undefined method when method actually exists.

To Reproduce

On App\Stage\DeserializeStage

    if (!is_object($user = $token->getUser())) {
        return;
    }
    if ($resourceClass === 'App\Entity\BlockedUser' && $operationName === 'create') {
        $deserializeObject->setBlocker($user);
    } elseif ($resourceClass === 'App\Entity\Ad' && $operationName === 'create') {
        $deserializeObject->setUser($user);
        $deserializeObject->setIsActive(true);
        // when user creating ad offer, add providedCategory if not already exists
        if ($deserializeObject->getIsOffer()) {
            // check if user providedCategory already include ad category
            if (!$user->getProvidedCategories()->contains($deserializeObject->getCategory()) ) { **** ERROR *****
                $user->addProvidedCategory($deserializeObject->getCategory());    **** ERROR *****
            }
        }
    }

On App\Entity\User

 /**
 * @return Collection|Category[]
 */
public function getProvidedCategories(): Collection
{
    return $this->providedCategories;
}

public function addProvidedCategory(Category $providedCategory): self
{
    if (!$this->providedCategories->contains($providedCategory)) {
        $this->providedCategories[] = $providedCategory;
    }

    return $this;
}

Expected behavior Should not error, as the methods does exist.

Platform and version Mac OS intelephense v 1.8.2

Hi @BernardA,

I'm not sure but this issue could probably be related to mine: [Bug] Broken parse of property types since v1.8.1 (worked fine under v1.8.0). Check if you still have the false positive error while downgrading the version of intelephense to 1.8.0.

If you get the following results, I think our issues are the same:	Intelephense version	Bug
1.8.0	No
1.8.1	Yes
1.8.2	Yes

How downgrade a VS Code extension to a previous version? Just like this:

Regards.

I went backwards to 1.8.0 and the problem was already there. Nice try though.

It would seem that intelephense is not smart enough to know that User is referring to the User::class.

I needed to add type hint as below:

    /**
     * @var User $user
    */

    if (!is_object($user = $token->getUser())) {
        return $deserializeObject;
    }
