[BUG] Unable to download server startup kit from dashboard

[Plachido]

While users can download their startup kits from the dashboard, the request for downloading the server startup kit fails. Said request is made from the project admin to http://10.101.190.50:4000/api/v1/servers/1/blob (dashboard is running on custom chosen port).

Despite the box with "Your download should be starting soon." appears, the request to the server fails (server answers with Internal Server Error)

Server details: Ubuntu 22.04.4 LTS, Python 3.10, nvflare 2.40

@Plachido thanks for reporting!

Just gathering more information, so the project admin when downloading admin package or client startup kits all work?
just that when trying to download the server startup kits it failed?

You say "server answers with Internal Server Error", do you have the log/error on the server side?

Thank you for answering!
I seem to be able to download everything (with users and admin) except for the primary start kit (from project admin account).
Here is the error raising inside the docker container:

In case you need it, I am also attaching the full container log of the container where I have done the following operations:

• PROJECT ADMIN: admin log in
• ORG ADMIN: user subscription (org admin with one site)
• PROJECT ADMIN: approved site
• PROJECT ADMIN: approved user
• ORG ADMIN: downlaoded Flare Console
• ORG ADMIN: downloaded Startup Kit for Client Site
• PROJECT ADMIN: downloaded Flare Console
• PROJECT ADMIN: downlaod of Server Startup Kit (Primary) Failed

@Plachido thank you for the details. It looks like this has to do with the usage of the IP including "http://" for creating the the directory storing the server startup kit, and this contains several illegal characters for a directory name, which causes the error in the request.

I can look into a fix for this, but in the meantime, if it is possible to use a fully qualified domain name (FQDN) instead of an IP address for the server (you could edit /etc/hosts and point the name to your IP), this issue can be avoided.

@nvkevlu @IsaacYangSLA can we add a check to throw error or something when user give input that contains illegal characters?
