missing path_params values

[wihe96]

Hi guys,

i used the extension for setting up the stream between firestore and bigquery.
After that i wanted to back-fill the data and noticed that the path_params are not back-filled.

To understand how my firestore looks like:

I have a collection called customer. Here I create and store the snapshots of each customer as I need it (document)
For each customer I have two further collections. 1. events 2. messages

Within the event collection I store each event ass a document.

Now when setting up the extension the extension is streaming path_params which contain the id of each document in the customer collection, so that i can connect both tables in bigquery, in other words i can check which customer made which events or which event was made by which customer.

When back-filling the data trough the cloud shell the path-params are not exported.

with JSON_VALUE function I can extract the value of the last column (path_params) of each changelog. However as mentioned before the path_params are not back_filled.

The extensions settings look like this:

I guess that the field "Wildcard column field with Parent Firestore Document IDS" set to true expoorts the path_params right ?
However when backfilling trough the google cloud shell, it doesn't ask for this Parent Firestore Document ids if these should be backfilled as well.
