API error 400, Request body was not parsable

Hello! Whenever I try to use the Twitch Command Line Interface I receive a the 400 error, body was not parsable. Attempted Content-Type: “application/json”,
“pagination”: {}
and I’m not sure why. Here is how I’m inputting the code into Windows Powershell:

twitch api post eventsub/subscriptions -b '{

“type”: “stream.online”,
“version”: “1”,
“condition”: {
“broadcaster_user_id”: “”
“transport”: {
“method”: “webhook”,
“callback”: “https://mycallbacksite.com/webhook/callback”,
“secret”: “”
