ACL is now optional for the Google Cloud Storage sink

ACL isn’t always required when creating objects in GCP Cloud Storage

Page source Edit this page

GCP Cloud Storage buckets with uniform bucket-level access don’t support setting ACL for objects inside them (HTTP 400 error is returned). Therefore, the Vector gcp_cloud_storage sink no longer supplies a x-goog-acl header by default.

Upgrade Guide

If you wish to set an ACL for your GCP object you’ll need to explicitly set the acl option:

 [sinks.gcp_cloud_storage]
   type = "gcp_cloud_storage"
+  acl = "projectPrivate" # change as desired

That’s it!
