Firebase storage add file reference to firestore

I am trying to get a form upload working to upload data to my Firestore db as well as upload an image to my firebase storage.

Individually I can do both, however outside of storing the exact URL of the uploaded image I can't seem to figure out how to programatically store the Reference to the image in my firestore.

In the console I can set the type to "Reference" enter image description here

But whatever I try programatically doesn't work:

Post image upload:

const url = await storageRef.snapshot.ref.getDownloadURL()
let imageRef = storage.ref().child(`test/${this.imageData.filename}`).ref
// let imageRef = storageRef.snapshot.ref
// let imageRef = storage.ref(`test/${this.imageData.name}`)

const docRef = await testImagesCollection.add({
   thumbnail: imageRef,
   dateCreated: firestore.FieldValue.serverTimestamp()
})

alert("upload succeeded", docRef.id)

I usually end up with: FirebaseError: Function DocumentReference.set() called with invalid data. Unsupported field value: a custom Reference object (found in field thumbnail)

If I have to I'll just store the URL but I rather not do that, if the console allows me to set a reference I should be able to do it programatically as well?!

Firestore reference types only work with references to other documents represented as DocumentReference objects. They don't work with references to objects in Cloud Storage. If you want to store a reference to an object in Cloud Storage, you should either store the path to the file in the bucket (as a string, not as a Reference object), or a download URL (whichever is more convenient for you).

If you have a Reference object, you can get a string path to it with its fullPath property.
