Hello, I have created a cisco iot control center sandbox - I'm able to authenticate and use the echo api successfully, however, when searching for devices there is an empty list of devices returned. It seems there are no virtual devices populated - according to the documentation: "DevNet will create an Advantage account containing virtual devices with historical data. These devices will continue to generate new data over time."
Here's an example device search request I'm attempting which returns an empty list of devices:
curl -X GET --header "Accept: application/json" --header "Authorization: Basic <YOUR-ENCRYPTED-CREDENTIALS>" "https://rws-jpotest.jasper.com/rws/api/v1/devices?modifiedSince=2016-04-18T17%3A31%3A34%2B00%3A00&pageSize=50&pageNumber=1" ;
