Cannot get graph to chart with postgresql

I am very new to Grafana and I am just trying to chart a simple graph. I run this query and in table view I do see rows being returned but nothing gets charted.

Ultimately, I would like to have a time series graph but when I change formats, I get 0 rows:

I took a look at anything that is similar and I found this Can't get data from MS SQL graphed but I checked and seems like all my time is in epoch format.

Any help or advise would be greatly appreciated. Thanks.
