** edit: can we pls move this topic under devnet sandbox? I'm still noob and this is my first post. sorry for any confusion. 

Hello all, 

I'm practicing Hank Preston's net prog basics video course. I was looking at python code on netprog_basics/network_controllers/apicem/troubleshoot_step3.py where the program should list the hops on the way between source and destination.

However, I'm getting status failed for my GET request (see below), anybody else experienced this as well? 

{
"response": {
"request": {
"sourceIP": "10.2.1.22",
"destIP": "10.1.15.117",
"periodicRefresh": false,
"id": "beae3cb8-d6ee-4072-b885-725ca9eee094",
"status": "FAILED",

EDIT: so in response body, I see failure reason 
failureReason": "Unable to retrieve links for  AP - AP7081.059f.19ca [ cd6d9b24-839b-4d58-adfe-3fdf781e1782]"

when  I check the AP, I see interfaceCount as null. Also, GET request to /interface/network-device/{{id}} returns 404, data not found. could it be the reason for status: FAILED?

Always on APIC-EM Sandbox doesn't have "live" network devices. What you see is the snapshot of network data at a particular moment - a static DB. I think the outcome of script you observed maybe true.
