Firebase - Query Document. Help!

Hello, I'm trying to make the Query Document functionality for firebase work. However, I keep on getting this error message:

[{"error":{"code":400,"message":"Invalid JSON payload received. Unknown name \"\": Root element must be a message.","status":"INVALID_ARGUMENT","details":[{"@type":"type.googleapis.com\/google.rpc.BadRequest","fieldViolations":[{"description":"Invalid JSON payload received. Unknown name \"\": Root element must be a message."}]}]}}]

Basically, I have a collection called "Orders" and I want to query the Document IDs given an Order ID and a Order Line ID. If written as SQL, it will be like this:

SELECT DOCUMENT_ID
FROM Orders
WHERE OrderID = '12345' and OrderLineID = '23456'

Can anyone help me make it work?

Hi @pulboron,

Could you please make a short screen recording elaborating a bit more on your use case? This will allow us to gain a better understanding of your concern.

Here you go: screen recording link

Basically my use case is the following:
1. I get all Order Updates from WooCommerce
2. Once I get Order updates, I Query if that order exists in Firebase using 2 columns: OrderID and OrderLineID
3. If it does not exist, Create new document/record in Firebase
4. If it exists, update the existing record in Firebase

I was able to get it working. Apparently, I needed to include data type in filter value instead of just putting the value there.

Thanks for the update @pulboron
