title: Can not insert data to the Table
body: <p>I'm trying to upload data from ERP-system (1C Enterprise) to Google BigQuery table.
  I'm using HTTP POST request as described here:
  <a href="https://cloud.google.com/bigquery/docs/reference/v2/tabledata/insertAll" rel="nofollow noreferrer">https://cloud.google.com/bigquery/docs/reference/v2/tabledata/insertAll</a></p>
  
  <p>I use the link: <a href="https://www.googleapis.com/bigquery/v2/projects/MyProjectId/datasets/1C/tables/Test_table/insertAll" rel="nofollow noreferrer">https://www.googleapis.com/bigquery/v2/projects/MyProjectId/datasets/1C/tables/Test_table/insertAll</a>
  where MyProjecId is like some-letters-6_digits
  1C - is id of my data set
  Test_table - is id of my table in 1C dataset</p>
  
  <p>The table has 2 fields:
  field1 - string - nullable
  field2 - string - nullable
