[multi-stream-activation] Events don't appear in GA4

[enestrkkn]

Trainings are completed and predictions have been running daily for purchase propensity pipelines. GA4 variables are provided as follows (multiple stream id):

_####################  GA4 VARIABLES  #################################
ga4_property_id        = "{property id}"
ga4_stream_id          = ["{first stream id}", "{second stream id}"]
ga4_measurement_id     = "{measurement id}"
ga4_measurement_secret = "{measurement secret}"

Predictions were successfully completed (whole pipeline results successful) and I can validate there are prediction outputs in bigquery tables respectively. However, events are not pushed to GA4 (controlled through UI and bigquery exports). Also, I see the log file of the activation step of the prediction pipeline is empty.

Measurement ID and secret are accurate and controlled bigquery and GA4 after 72 hours as well. What should be done to control further or is there an implementation issue?
