go-licenses csv "github.com/google/trillian/server/trillian_log_server" gives me empty result

I've been trying the examples in readme, but they all give me empty result. I am using golang version:

$ go version
go version go1.16.3 linux/amd64

The example from the README also does not work for me out of the box. Instead of an empty result like the OP, I get an error and the suggested action does not help.

$ go-licenses csv "github.com/google/trillian/server/trillian_log_server"
