[Bug] Unable to import Notion data in self-hosted instance - Minio presigned URL error

[domsilvestre]

Bug Description

When trying to import a Notion export file in a self-hosted AppFlowy instance, the import fails with a Minio presigned URL error. The import works fine on AppFlowy Cloud but fails on self-hosted setup.

How to Reproduce

1. Set up AppFlowy-Cloud with Minio storage on AWS EC2
2. Configure Minio in docker-compose.yml and .env
3. Open AppFlowy desktop app
4. Try to import Notion export file
5. Get "3 tasks pending" message
6. After a while, get error with presigned URL

Expected Behavior

The Notion export should be successfully imported into the self-hosted AppFlowy instance, just like it works on AppFlowy Cloud.

Operating System

• Server: Amazon Linux 2023 (EC2) - Client: macOS

AppFlowy Version(s)

• AppFlowy Desktop: 0.7.3 - AppFlowy-Cloud: Latest from main branch

Screenshots

Additional Context

• Successfully imported the same Notion export on AppFlowy Cloud
• Minio is properly configured and running (ports 9000 and 9001)
• AWS security group has all necessary ports open
• Tried clearing pending tasks in database
• Tried different Minio configurations and CORS settings
• Unable to transfer data from cloud to self-hosted instance

@domsilvestre If you are in development mode, you can check the frontend app debug console. It seems like a upload file issue
