Adobe API +POST request + Data is being pulled as zero's

I am able to connect to adobe API using JWT.

while i try to send a JSON response using POST via requests , I get back below response where all the data is coming across as zero's .
not sure wht the issue is , would be great to get a response on this front !!.
