Mock server causing client to panic

[a-dot]

I tried running the mock server

[a-dot ~/repos/ch-go/internal/cmd/ch-bench-server (main)]$ go build
[a-dot ~/repos/ch-go/internal/cmd/ch-bench-server (main)]$ ./ch-bench-server 
starting with chunk of 1.6 MB

And then tried running the ch-write-bench-faster benchmark. (I had to add one line to specify port 9001 instead of the default 9000):

[a-dot ~/repos/ch-bench/ch-write-bench-faster (main)]$ go build
[a-dot ~/repos/ch-bench/ch-write-bench-faster (main)]$ ./ch-write-bench-faster

But then I get this panic. How do I use the mock server?

I took a closer look at the mock server and realized it's not really a mock server.
