Getting MismatchingDocblockParamType error even when there's no docblock

[toviet]

Hi,

Since upgrading to v5.2.1, Psalm seems to show these weird MismatchingDocblockParamType errors on my codes which have no docblock at all.

For example

$featureResult = $this->cache->get(
        $key,
        function (ItemInterface $item) use ($feature, $dataCache) {
            $item->expiresAfter(Time::SIX_HOURS_IN_SECONDS);

            return $this->compileFeatureResult($feature, $dataCache);

And I get:

Service.php:173:27: MismatchingDocblockParamType: Parameter $item has wrong type 'Psr\Cache\CacheItemInterface', should be 'Symfony\Contracts\Cache\ItemInterface' (see https://psalm.dev/141)

Even more odd that this only happens on a selected of files which use similar caching pattern, but not all of them.

Does anyone know what's the issue here?

Can you check what the docblock of the get() function on cache is?

The cache is drawn from Symfony Memcache Adapter (https://symfony.com/doc/current/components/cache/adapters/memcached_adapter.html) so should be the standard. We have other places where the same adapter is used but having no Psalm error at all.
