Undefined index: scope_closer

[snapshotpl]

After update my code to 7.4 by Rector phpcs throw some internal exception.

Fatal error: Uncaught PHP_CodeSniffer\Exceptions\RuntimeException: Undefined index: scope_closer in /var/www/vendor/slevomat/coding-standard/SlevomatCodingStandard/Helpers/UseStatementHelper.php on line 195 in /var/www/vendor/squizlabs/php_codesniffer/src/Runner.php:606

@snapshotpl What version do you use? What code does throw this error?

[snapshotpl]

v6.1.5. I don't know which file cause this error. I don't see any useful details in output to find it out.

[kukulich]

You can use verbose options for PHPCS.

[snapshotpl]

Got it! This is simplified version but still causes error:

<?php

class MyClass
{
    public function __construct() {
        if (
            $this->valid(fn(): bool => 2 > 1)
        ) {

        }
    }

    private function valid(callable $callable): bool
    {
        return $callable();
    }
}

Problem is fn in if condition

@snapshotpl Thank you for your report. However, it's a bug of PHPCS itself. Please report it directly to PHPCS. The T_CLASS token does not have scope pointers information.

@snapshotpl I've prepared a workaround for now: 4c88f6c
