Hi all,

Starting with Warp10 for a few days now and quiet happy so far with what I 
achieved ! 

Follwoing the cyclone tutrial on Warp10 10.2.6 on my local machine I met an 
issue around attributes.

Dataset is there and we can see the "name" attribute : 
https://warp10.io/assets/files/ibtracs-2010-2015.gts

But for step 5 of the Category 1 tutorial "Names of Tropical Cyclones in 
2015", the code did not work for me 
(https://warp10.io/content/04_Tutorials/05_Cyclones_on_Sandbox/10_Category_1)

If I do 

[ 
  $read_token
  'gov.noaa.storm.wind'
  {}
]
FIND

The JSON output is always empty for the "a" field.

Like :

[
{"c":"gov.noaa.storm.wind","l":{"serial":"2012189N10262",".app":"io.warp10.bootstrap"},"a":{},"la":0,"v":[]},
...
]

Same if I do a FETCH.

[{"c":"gov.noaa.storm.wind","l":{"serial":"2015251N31298",".app":"io.warp10.bootstrap"},"a":{},"la":0,"v":[[1441951200000000,35.69999998435378,-60.30000007711351,40],[1441929600000000,34.299999992363155,-60.70000000298023,40],[1441908000000000,33.19999996572733,-60.90000000782311,40],[1441886400000000,32.19999998342246,-60.90000000782311,40],[1441864800000000,31.599999968893826,-60.90000000782311,45],[1441843200000000,31.19999995920807,-60.80000004731119,45],[1441821600000000,30.89999999385327,-60.80000004731119,45],[1441800000000000,30.799999991431832,-61.000000052154064,40],[1441778400000000,30.799999991431832,-61.20000005699694,35],[1441756800000000,30.799999991431832,-61.40000006183982,35],[1441735200000000,30.799999991431832,-61.600000066682696,30],[1441713600000000,30.89999999385327,-61.9000000320375,25],[1441692000000000,31.09999999869615,-62.20000008121133,20]]}

And if I do something like:

[ 
  $read_token
  'gov.noaa.storm.wind'
  {}
  '2016-01-01T00:00:00.000z'  // End date
  '2010-01-01T00:00:00.000z'  // Start date
]
FETCH 
// It is possible to avoid fetching data for the whole the year but we keep it 
simple for now
0 GET
ATTRIBUTES

It's still empty.

I deleted the gts and tried to reupload it from curl or from studio and 
it's always the same.

Any idea on how to fix this?

Thanks,
Nicolas
