Drilldown on search with strftime eval keeps opening blank search. I have tried different permutations encoding but it keeps opening a blank search.

[pietertruter1]

search:
| makeresults
| eval lastModifiedTime = "1570536921"
| eval lastModifiedTime = strftime(lastModifiedTime, "%Y-%m-%d %H:%M:%S")
| table lastModifiedTime

drilldown
search?q=%7C%20makeresults%20%0A%7C%20eval%20lastModifiedTime%20%3D%20%221570536921%22%0A%7C%20eval%20lastModifiedTime%20%3D%20strftime(lastModifiedTime%2C%20%22%25Y-%25m-%25d%20%25H%3A%25M%3A%25S%22)%0A%7C%20table%20lastModifiedTime
