Missing accessKey error, but I am providing the access key

[Noelia Osés Fernández]

Hi all,

I'm new with Prediction IO and in order to understand how it works I'm
customizing the Universal Recommender template to a very simple case (the
handmade example works).

I have unzipped the universal recommender and changed the folder name to
TinyApp.

I have then used 'pio app new TinyApp' to create the app id and access key.

I'm now trying to add some data (I'm using the proper access key as listed
in pio app list instead of *myaccesskey*):

curl -i -X POST http://localhost:7070/events.json?access_key=*myaccesskey*
-H "Content-Type: application/json" -d '{
  "event" : "view",
  "entityType" : "user",
  "entityId" : "u1",
  "targetEntityType" : "item",
  "targetEntityId" : "i1",
}'

But I get the following error message:

HTTP/1.1 401 Unauthorized
Server: spray-can/1.3.3
Date: Tue, 03 Oct 2017 13:06:58 GMT
Content-Type: application/json; charset=UTF-8
Content-Length: 32

{"message":"Missing accessKey."}

Why is this? What am I doing wrong?

Thank you very much for your help!

Noelia
