here is my code:
override suspend fun updateDocument(
        productId: String,
        updates: Map&lt;String, Any&gt;
    ): Resource&lt;Boolean&gt; {
        return withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
            try {

                val documentSnapshot = db.collection(INVENTORY)
                    .document(productId)
                    .get()
                    .await()

                if (documentSnapshot.exists()) {
                    Timber.tag(INVENTORY_TAG).d("Document exists")

                    db.collection(INVENTORY)
                        .document(productId)
                        .update(updates)
                        .await()
                    Resource.Success(true)
                } else {
                    Timber.tag(INVENTORY_TAG).e("Document does not exist")
                    Resource.Error(Exception("Document with ID $productId does not exist"))
                }
            } catch (e: Exception) {
                Timber.tag(INVENTORY_TAG).e(e)
                Resource.Error(e)
            }
        }
    }
