If the value of a proxy target did not exist in the database when instantiated (and no default value was given), it is not updated once the database node is created afterwards. This only applies to a created proxy's root value.

To replicate:

// Create proxy without default value
const proxy = await db.ref('chats/chat1').proxy(); 
// proxy.value is now a Proxy whose .valueOf() === null
console.assert(proxy.value.valueOf() === null);

// Create the target
await db.ref('chats/chat1').set({ title: 'New chat' });

// proxy.value now SHOULD be a Proxy whose .valueOf() is the object { title: 'New chat' }
// However, it is still null
console.assert(proxy.value.valueOf() !== null); // Fails assertion
