In Compass 1.22.1, Date and ISODate objects evaluate to {} in the embedded shell:

>  foo = new Date("2020-10-07")
< {}

> foo.toJSON()
< '2020-10-07T00:00:00.000Z'

> typeof foo
< 'object'

The expected result would be an ISO date similar to the toJSON() output. Example from standalone mongosh:

> foo = new Date("2020-10-07")
2020-10-07T00:00:00.000Z
