node.js - how We can count cloud Firestore document of collection, based on document field condition?

Question

I want to count the document of collection based on fields. I found one reference but giving me error Property 'select' does not exist on type 'CollectionReference. Below is my firestore service class code. which I applied to fetch the count.

firestore().collection(collectionName).select(documentFieldName).get().then(
(snapshot) => console.log(snapshot.docs.length));

Can any one please suggest there is other way to do ?

Now tried with this pic of code

  const a = await firestore().collection(collectionName).where('createdBy', 
 CONDITIONS.EQUALS, reportType).get().then(a => (a.size)); 

It giving me as proper response number but added some string text "Invalid status code" I am not sure why added this string

Invalid status code: 19
