Can not start trained models.insert

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Opened API Explorer
2. Made "Authorize using OAuth 2.0 On"
3. Selected "prediction" service > "v1.5" > "trainedmodels.insert"
4. Entered "fields" as "id"
5. Changed request body as follows:
{
 "id": "tureng",
 "storageDataLocation": "tureng/tureng.csv"
}
6. Clicked Execute

What is the expected output? What do you see instead?
- I expect it to insert my data into prediction training data. But it gives now 
"500 Internal Server Error". Previously it was not giving this error but it was 
also not creating my training data. (I was checking with trainedmodels.get but 
it was returning "not found" when I enter the same id)

What version of the product are you using? On what operating system?
v1.5

Please provide any additional information below.

Deleted everything and started again but this time trainedmodels.get returs 
this always after insert:

404 Not Found

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "notFound",
    "message": "No Model found. Model must first be trained."
   }
  ],
  "code": 404,
  "message": "No Model found. Model must first be trained."
 }
}
