Firestore to query by an array's field value

I'm trying to run a simple query, where I search for a document that contains a value inside an object array.

For instance, look at my database structure:

I want to run a query similar to this:

db.collection('identites').where("partyMembers", "array-contains", {name: "John Travolta"})

What is the correct way to achieve this, is it even possible with Firestore?

Thanks.

The array-contains operations checks if an array, contains a specific (complete) value. It can't check if an array of objects, contains an item with a specific value for a property.

The only way to do your query, is to add an additional field to your document with just the value you want to query existence on. So for example: partyMemberNames: ["John Travolta", "Olivia Newton"].
