Empty array response for heart rate variability data

[RishabBaisakh]

I am getting an empty array for the heart rate variability data, my client_id is 238WHZ.

Here is the api is am using, 

https://api.fitbit.com/1/user/-/hrv/date/<start_date>/<end_date>.json

Hi @RishabBaisakh 

The endpoint syntax looks correct.   Have you verified your account has HRV data in it?   Please click on the "Health Metrics" tile in the Fitbit mobile application.

Hi Gordon, I'm running into this same issue. I can see HRV metrics in my app. Any ideas why I might be getting an empty response?

Hi @ifeelfine 

If you see the data in Fitbit mobile application, then I would 

1. double-check the HRV endpoint syntax being used
2. double-check the user id being used.
