UI Bakery Asset Storage Configuration Issue with MinIO

[gmunaro]

Environment:

UI Bakery On-Premise (latest)
Docker Swarm
Traefik as reverse proxy
MinIO as S3 storage
Portainer for management

Issue:
When trying to upload an image to a component, I'm getting the error:

Asset storage not configured on your instance

What I've tried:

1. Configured MinIO with:
   Separate endpoints for API (s3api.domain.com) and frontend (s3.domain.com)
   Created bucket with public read access
   Verified MinIO credentials work correctly
   Set up storage configuration in UI Bakery with:
   S3 compatible storage
   All required environment variables
   Proper endpoints and credentials

Current Configuration:

Here's my docker-compose file with the storage configuration (sensitive data replaced with placeholders):

version: '3.8'

Logs:
When trying to upload, I get this error in bakery-back logs:

Failed to upload to the storage. reason=Asset storage not configured on your instance
com.akveo.bakery.storage.exception.StorageNotConfiguredHttpException: null

Questions:

Is there any specific version of UI Bakery that works better with S3 storage?
Are there any additional environment variables needed beyond what's in the documentation?
Could this be related to the way Docker Swarm handles environment variables?
I'm happy to debug this on a call if needed, as this seems to be a critical functionality for our implementation.

Additional Info:

MinIO is working correctly with other applications
All services are running and healthy
Network connectivity between services is confirmed working
