[Bug] Import workspace works on the cloud instance, but not on localhost

[ulysse42]

Bug Description

I'm setting up a self-hosted Appflowy server for myself on my laptop. I tried to import my existing workspace from "local", so I did the following :
In my local session, I went to Settings > Manage Data > Backup your workspace
Everything's fine, the ZIP is correctly created.
Then I switch to "appflowy self-hosted" in cloud settings, with the address http://localhost (hosted on port 80, I have correctly access to the admin panel, the web app, and I can connect and create workspaces in the desktop app)
and from the desktop app connected to the Appflowy cloud server running on localhost, when I try to import my workspace, I get an error (see screenshot below) "Invalid file format".
So to see if the backup is corrupted or something, I go back to cloud settings and connect to Appflowy cloud, and from there, the import works fine, and I get my data in the cloud instance. From there I also do a new ZIP backup just in case some magic happens behind the scenes.

What I tried:

• import a zip backup from my local workspace in my self-hosted instance (doesn't work)
• import a zip backup from my cloud account into my self-hosted instance (doesn't work)
• import a zip backup from my local workspace to my cloud account (works!)
• both in 0.9.7 and 0.9.8

Am I doing something wrong, is this a bug with the "localhost" FQDN ?

How to Reproduce

Install 0.9.7
Create a local workspace (anonymous)
Backup as a ZIP
Deploy a self-hosted instance on localhost, default ports, default config other than localhost address
In the desktop app, connect to your localhost instance by choosing Self-hosted, address "http://localhost"
Once in your self-hosted instance, try to import your zip backup

Expected Behavior

It should import the workspace, as it does on the public cloud instance

Operating System

Arch Linux

AppFlowy Version(s)

0.9.7, 0.9.8

Hi @ulysse42, did you set up Mino on your local deployment? I've received similar reports before. It's a deployment issue.

I didn't modify any minio config, the pod is running and healthy yes. I'll check the logs and come back asap.

No logs on Minio during the failure, every request is a 200 OK on nginx and gotrue during the failure

Can you try installing this version: 0.9.9-250909-0457 and then upload the zip file to your self-hosted server again? If it still fails, please upload the log files.
