2. Meta 1.3.3

2. Wait for indexing

1. Reindex fails because it can't find the class

There was an attempt to support both the older and current versions of Magento.

Unfortunately the implementation does not work currently.

if (class_exists(\Magento\Framework\Mview\View\ChangeLogBatchWalkerFactory::class)) { // @phpstan-ignore-line

The issue is on this line.

The problem is that class_exists PHP function searches for the class in a case insensitive manner and will thus always return ChangeLogBatchWalker and never ChangelogBatchWalker. (in fact PHP treats classes in case insensitive manner in general, but the autoloader does not)

My suggestion would be something like this:

        $changeLogWalkerFactory = $this->objectManager->create(
            \Magento\Framework\Mview\View\ChangeLogBatchWalkerFactory::class // @phpstan-ignore-line
        );
        if (get_class($changeLogWalkerFactory) == "ChangeLogBatchWalkerFactory") {
            return $changeLogWalkerFactory->create(
                \Magento\Framework\Mview\View\ChangeLogBatchWalker::class // @phpstan-ignore-line
            );
        }

        $changelogWalkerFactory = $this->objectManager->create(
            \Magento\Framework\Mview\View\ChangelogBatchWalkerFactory::class // @phpstan-ignore-line
        );
        return $changelogWalkerFactory->create(
            \Magento\Framework\Mview\View\ChangelogBatchWalker::class // @phpstan-ignore-line
        );

get_class will return the actual class name in use, case sensitive.
