Union return type with macro fails with "Call to undefined method ReflectionUnionType::getName()"

[carestad]

Versions:

• ide-helper Version: 2.10.0
• Laravel Version: 8.53.1
• PHP Version: 8.0.9

Description:

In my AppServiceProvider.php I have added a macro for the Stringable class in Laravel:

Stringable::macro('fromJson', fn(bool $assoc = false): array|object => json_decode($this->value, $assoc));

THe array|object part there causes php artisan ide-helper:generate to fail with the following error:

  Call to undefined method ReflectionUnionType::getName()

  at vendor/barryvdh/laravel-ide-helper/src/Macro.php:60
     56▕         if ($method->hasReturnType() && !$this->phpdoc->hasTag('return')) {
     57▕             $builder = EloquentBuilder::class;
     58▕             $return = $method->getReturnType();

I have also tested to change fn() to function() like so:

Stringable::macro('fromJson', function(bool $assoc = false): array|object {
    return json_decode($this->value, $assoc);
});

But to no avail I'm afraid. If the return type is only array or object it works.

I think this was fixed with https://github.com/barryvdh/laravel-ide-helper/pull/1148 but there's no new release yet; can you check with 2.9-dev if it works for you?

@mfn Yep, it seems to work well with dev-master :+1:

Have the same issue and can confirm using dev-master fixed my issue as well!

Setting a dep on dev-master is far from ideal. @barryvdh Can we please get a new release/tag?

New releases where made -> closing
