Missing Column names when count == 1 for csv data

My result set is missing the column names when count == 1. I tried using &array=true and other parameters, but it only returns column names when count > 1.

$ curl -H ‘X-API-Key: REDACTED’ “https://my.api.mockaroo.com/test/RA123/?count=1
Shoes,100.00

$ curl -H ‘X-API-Key: REDACTED’ “https://my.api.mockaroo.com/test/RA123/?count=2
Description,Amount
Shoes,100.00
Pants,200.00

My Handler script is nothing special, last line is:
generate params[‘count’]
