Events not getting forwarded from BQ to GA4

[parasvishnoi]

Hi,
I've been trying to send events from BQ table to GA4 using tcrm_bq_to_ga4 dag. I've encountered 2 different issues so far:

1. I created a new BQ table according to the schema mentioned in the below link and then triggered the TCRM dag. The entries seem to be created in tcrm_monitoring_table and the DAG ran successfully but the events are not visible on GA.
2. I tried to trigger the dag again with different data in the table but now even the entries in monitoring table don't get created but the DAG finishes successfully.

Let me know what can I be doing wrong.
I've created a new event on Google Analytics dashboard and using gtag and measurement_id as configuration to send events.
