Lab validation slowms missing threshold

Lab validation slowms missing threshold. “You need to specify the millisecond threshold for slow operations” but I did.
vagrant@m103:/etc$ mongo newDB --host 192.168.103.100:27000 -u m103-admin -p m103-pass --authenticationDatabase admin --eval ’
db.setProfilingLevel( 1, { slowms: 50 } )

MongoDB shell version v3.6.12
connecting to: mongodb://192.168.103.100:27000/newDB?authSource=admin&gssapiServiceName=mongodb
Implicit session: session { “id” : UUID(“2e547e5a-aa29-4be5-942b-4affb544b8b9”) }
MongoDB server version: 3.6.12
{ “was” : 1, “slowms” : 50, “sampleRate” : 1, “ok” : 1 }
vagrant@m103:/etc$ validate_lab_different_logpath
