404 when serving block device files

[BlackFuffey]

I wanted to use miniserve to transfer raw disk partition over network, but it would always return 404 not found instead of sending the file.

I used the following command line to serve

miniserve -i 10.0.0.240 /dev/nvme0n1p3

And doing wget "http://10.0.0.240:8080" would return 404 Not Found and log

[ERROR] Route / could not be found

using the same commands to transfer a regular file works as intended.
