I am working with the development playground for the first time and am attempting to access the "Create Customer" endpoint for the in-app provisioning API. When I hit run, I keep getting a "received fatal error: handshake_failure" in the response. I've tried regenerating the keystore several times, different API keys for the secret token, etc. Nothing I do seems to make a difference and the error response is to vague to help me figure out where the issue is. Any help is appreaciated!
