null values in data stop script

[jimlynnjulian]

The title pretty much says it all. When I try to convert a subset of a file of json lines, the script stops. The word 'null' is used to fill gaps in the data. "Trying to access array offset of type null in (file.json)." Uncaught TypeError argument #1 must be of type array, null given in (file). json2csv.class.php, line 21.
