Warning: Illegal offset type in isset or empty in \vendor\phpcollection\phpcollection\src\PhpCollection\AbstractMap.php line 134

when trying do deserialize a prieviously serialized object with jms-serializer:

$json = $this->serializer->serialize($object, 'json', SerializationContext::create()->enableMaxDepthChecks());
$this->serializer->deserialize($json, 'json', SerializationContext::create()->enableMaxDepthChecks());

[JarJak]

hello?

[judgej]

@JarJak I'm guessing jms-serializer is out of scope for this package. If you need this fixed, then you are going to have to dig into it yourself and report back with more details.

[doofer]

For future reference, your function arguments are not ok for deserialize: You need the jsonText, objectClassName, 'json' or 'xml' (type), DeserializationContext

[JarJak]

@doofer you are probably right. Anyway it would be nice to check key type before using isset(). Like:

    public function containsKey($key)
    {
        if (is_array($key) || is_object($key)) {
            //throw...
        }
        return isset($this->elements[$key]);
    }

[discordier]

@JarJak Which could be wrong for the object case in some cases, as we can provide a __toString().

[JarJak]

@discordier so:

    public function containsKey($key): bool
    {
        if (is_array($key) || (is_object($key) && !method_exists($key, '__toString')) ) {
            //throw...
        }
        return isset($this->elements[$key]);
    }
