improvement: Update interface{} casting to avoid runtime panic

[GokselKUCUKSAHIN]

Description

This PR enhances type safety when accessing the map fields.

Before:

if matchAll, exists := m["match_all"]; exists {
	matchAll.(Object)[key] = value
}

In this example, if match_all exists but isn’t castable to Object, a runtime panic occurs.

After:

if matchAll, ok := m["match_all"].(Object); ok {
	matchAll[key] = value
}

This change ensures that the key exists and is safely cast to Object before modifying it, preventing potential panics.
