"error": "invalid character 's' looking for beginning of value"

Hi @brocaar, Thanks for your open soure item.
I used your ChirpStack on the Ubuntu16.04, and open the http://localhost:8080/api# via firefox. I try to use the POST of UserService, of course I used your example to define the body value. But it failed. erro info as topic shows. Could you give me some suggestion about the error, and how should I define the value?
Waiting for your reply!

Sorry, I’ve solved it. That caused by the error organizationID. Sorry for troubled you!
