Content-type form with POST is not working

[visola]

I've tried the following request:

http +profile '/api/v1/lists?api_key={privateKey}' -X POST -d 'name=test' -H 'Content-Type:application/x-www-form-urlencoded'

The output shows the data is coming through:

Content-Type: application/x-www-form-urlencoded
>> name=test

But the server doesn't seem to be receiving the data in the correct format because it returns a 400.

Trying the equivalent in cURL works:

curl 'http://hostname/api/v1/lists?api_key=***' -H 'Content-Type:application/x-www-form-urlencoded' -d name=test -v
