Hi FME Community,

I came across the following notice in the AWS S3 API documentation about the Owner object:

“Beginning November 21, 2025, Amazon S3 will stop returning DisplayName. Update your applications to use canonical IDs (unique identifier for AWS accounts), AWS account IDs (12-digit identifiers), or IAM ARNs (full resource naming) as a direct replacement for DisplayName. Between July 15 and November 21, 2025, you will begin to see an increasing rate of missing DisplayName values in the Owner object.”
Reference – AWS Documentation

Could you please confirm whether this upcoming change will (or might) affect how FME Flow interacts with Amazon S3 — for example, any components that depend on the Owner object or its DisplayName field?

Environment:

  • OS: Ubuntu

  • FME Flow 2023.2.1 and 2025.1.1

Thank you in advance for your guidance!

Hi ​@sei, 

This change should not affect FME Flow features (S3 external action in Automations, S3 subscriber in notifications, S3 resource connections, etc) as they do not rely on the DisplayName field.
