Thank you Alexander, but I got it figured out. I was storing
sessionStartTime as a Unix timestamp but did not provide any mapping, so
the field type was set to be a double. Once I explicitly mapped
sessionStartTime to be a date my query results started including the
key_as_string field.

GET /_all/_search
{
aggs: {
totalsByHour: {
date_histogram: {
field: sessionStartTime,
