I'm trying to formulate a body for my load job (multipart) into Bigquery. Following the example on <https://cloud.google.com/bigquery/loading-data-post-request#multipart>:

```
-foo_bar_baz
Content-Type: application/json; charset=UTF-8

{
  "configuration": {
    "load": {
      "sourceFormat": "NEWLINE_DELIMITED_JSON",
      "schema": {
        "fields": [
            {"name":"word","type":"STRING"},
            {"name":"word_count","type":"INTEGER"},
            {"name":"corpus","type":"STRING"},
            {"name":"corpus_date","type":"INTEGER"}
        ]
      },
      "destinationTable": {
        "projectId":"myproject",
        "datasetId":"mydataset",
        "tableId":"mytable"
      }
    }
  }
}

--foo_bar_baz
Content-Type: */*

[MY-JSON-DATA]
--foo_bar_baz--

```

But I get the message from google saying:

"message": "Job configuration must contain exactly one job-specific configuration object (e.g., query, load, extract, spreadsheetExtract), but there were 0: "

If I look at the docs at <https://cloud.google.com/bigquery/docs/reference/v2/jobs#configuration.load> it seems that the sourceUris[] is required but the example doesn't include it. My data is not in the google cloud storage but in the request. Why doesn't it detect my load details? 

Thanks for any help. //Leif
