GCP Bucket output does not write anything to bucket

[mattdecorniquet]

Describe the bug

I'm experiencing exactly the same issue described in #313 (which was fixed in #312):
I've configured credentials for a bucket in the GCS output section, the k8s cluster is generating logs and sending them to falco and then to falcosidekick.
The latter has the following in its logs GCPStorage - Upload to bucket OK, debug mode show the proper payload but nothing is created on the bucket.
Trying to output those same logs with a default loki config works flawlessly.

How to reproduce it

• Configure the GCP Bucket output in sidekick.
• Generate a debug event.
• Observe GCPStorage - Upload to bucket OK
• Observe no new objects or API calls in the target GCP bucket

Expected behaviour

Logs should be written in the target GCP bucket when falcosidekick says it uploaded successfully.

Environment

GKE, 9 nodes on Google container-OS. Falco and falcosidekick both installed with official helm chart with sidekick.enabled=true.
We're using argocd to manage helm.

• Falco version:
  helm chart is falco-4.2.2 so falco is 0.37.1 and falcosidekick is 2.28.0

Thanks for this report. I didn't implement the GCS output myself, I'll try to find some help.

This issue should be fixed in the upcoming 2.29
