Solution 1

You can solve theese problems by using this code

curl -X POST -u "CONVERSATION_USERNAME":"CONVERSATION_PASSWORD" -H "Content-Type:application/json" -d "{\"input\": {\"text\":\" \"}}" "https://gateway.watsonplatform.net/conversation/api/v1/workspaces/CONVERSATION_ID/message?version=2016-07-11"

In your —-header option the first character isn’t a normal hyphen (U+002d). Instead it’s an em dash (U+2014). Change it to a normal hyphen and things should work as expected.
