Wrong start/end time in response using client health intent API with DNA Center

[wwvan]

I would like to know the Health of my Clients, and so I do send to the sandbox DNAC

https://{{dnac}}:{{port}}/dna/intent/api/v1/client-health?startTime=1565449472000&endTime=1565622272000

The reply gives me the ecutionId : "7f858cfa-a93e-405e-b83c-66bb34a5308e",

With the get https://sandboxdnac.cisco.com/api/dnacaap/v1/dnacaap/management/execution-status/7f858cfa-a93e-405e-b83c-66bb34a5308e

I get following Reply:

}

Questions:

1. Why has the response other start/end time as in the request??

2. Why I receive an error??

Thanks in advance

I will start investigating from the second question. Looks like there is a "SyntaxError: Invalid JSON:", valid the JSON format first.

Regarding the epoch time is off. If I remember correctly, DNAC takes a snapshot every X min and save to DB. When the API make a query, it's not taking the "real time" snapshot as you requested, but taking from the DB with the time close to your requested time.
