Unable to access the key from proxy object – javascript

When I console the object, it’s printed as Proxy. It has nested objects and strings. I’m able to access all of the keys (exept one) using dot operator and they are printed in console when I do JSON.parse(JSON.stringify(proxy_object_example)). The one of the keys whose value is object becomes undefined when i try to access using dot operator. Still, Im able to see that object in console within Target of Proxy object. I tried _.cloneDeep but no luck.

Note: This is happening in project based on vue3 version but not sure which is what creating the problem.
