Getting "Request error / Sorry, we shouldn’t have let this happen. Please review your request"

Trying to work with a REST API from the Slurm job scheduler, and when I make a request via curl, all is fine. But, when I try to use HTTPie (Windows binary), I get the following screen:

But when I look at the call / response stream from HTTPie thru Wireshark, I see the following:

wireshark_slurm_rest_call.txt

Why is HTTPie not displaying the response correctly? Is it a setting I need to change? (new to HTTPie here...)
