PHP 8.1 : Undefined index scope_closer with Enum

[dimitriBouteille]

Describe the bug

When I want to analyze the following code, I have the following error: An error occurred during processing; checking has been aborted. The error message was: Undefined index: scope_closer in /vendor/squizlabs/php_codesniffer/src/Tokenizers/PHP.php on line 2836.

namespace Reflet\EInvoice\Model\Config\Source;

/**
 * Class ModeProvider
 *
 * @package Reflet\EInvoice\Model\Config\Source
 */
enum ModeProvider: string
{

    case Donation = 'donation';
    case Default = 'default';

    /**
     * @return \Magento\Framework\Phrase
     * @throws \Exception
     */
    public function label(): \Magento\Framework\Phrase
    {
        return match($this) {
            self::Donation => __('Donation'),
            self::Default => __('E-Invoice'),
        };
    }
}

Expected behavior

There should normally be no error with the code mentioned just before.

Versions (please complete the following information):

• OS: Linux
• PHP: 8.1
• PHPCS: 3.7.1 (stable)

I have a suspicion this may be related to/the same underlying issue as #3750... (untested/unconfirmed, but probably a good idea to look at both code samples when addressing either these)

@dimitriBouteille I've just tested your code sample on PHP 8.1 with both PHPCS 3.7.1 as well as master and I cannot reproduce the issue.

Please provide additional information with which the issue can be reproduced if you still see the issue. If not, please close the issue.

[jrfnl]

Note: the scope_closer index is also not referenced in or around line 2836, I'd have to go back to v 3.6.0 to find a reference to scope_closer on that line. As enums weren't supported until v 3.7.0, that would explain it, but would also mean that the version which the OP claims to use is incorrect.

Hye @jrfnl

I do not reproduce the bug also:)
