JSON Key Lookup

Hi there,

Curious if anyone has any good suggestions on the below problem. We are trying to get the keys from a JSON array object. The keys unfortunately are dates and are dynamic. For example, the below works fine, but it's hard-coding "09/03/2017". Any way to get all the keys from the object properly? Worth noting that index(local!list, 1) does not work in the below case.
=with(
local!json: "{
""09/03/2017"": {
""total"": 5
},
""10/03/2017"": {
""total"": 5
}
}",
local!list: a!fromJson(local!json),
index(local!list, "09/03/2017")
)
