Detector failing on certain inputs

[MichaelSheinman]

I've been playing around with the detector at (https://openai-openai-detector.hf.space/), and I noticed that there are some inputs that lead to the detector getting stuck on a "Predicting..." screen.
I consistently get the error with this input as a substring: docker swarm init --advertise-addr

In the developer console, I get:

It seems the server fails to respond with this sort of input. I am not sure what's special about this input because the server works just fine if I was to say change the "a" to "b".
