+ ignoredLinesCount (optional, number) - Number of lines to skip at the beginning of the file. If ignoredLinesCount is specified, the withoutHeaders option will be ignored.
+ treatValuesAsNull (optional, array[string]) - (Snowflake and BigQuery only) Array of string values that should be imported as NULL values. The default value is `['']`. Some other common values you might consider are `'\N'` or `'null'`. **Currently only single value is allowed**, but it still must be sent as array to allow future expansion.

Specific behavior of BigQuery:

* If the `treatValuesAsNull` parameter is empty array in the request, no values will be converted to NULL. Internally, the value `_\_KEBOOLA_IMPORT_AS_NULL_\_+UUID` will be used, e.g. `_\_KEBOOLA_IMPORT_AS_NULL_\_4b340550242239.64159797`. Such a value is highly unlikely to be present in the data, so no value will be converted to NULL.
