type error 0:0-0:0: missing object properties

[russorat]

the following query gives the error: cannot add type constraint @ 5:15-11:6: type error 0:0-0:0: missing object properties (_check_id, _check_name)

but i feel like it should work. I think it has something to do with the exists function. this is in cloud2

from(bucket: "_monitoring")
  |> range(start: -60d)
  |> filter(fn: (r) => r._measurement == "statuses" and r._field == "_message")
  |> map(fn: (r) => ({ 
    _time: r._time,
    _value: r._value,
    _check_id: if exists r._check_id then r._check_id else "Unknown",
    _check_name: if exists r._check_name then r._check_name else "Unknown",
    _level: if exists r._level then r._level else "Unknown"
  }))

Any solution ? getting the same error 500 Internal Server Error: {"error":"cannot add type constraint @ 15:10-23:7: type error 0:0-0:0: missing object properties (review_id)"}

@sathishsms Are you seeing this in cloud also? The original report is years old, making this extra curious.

I did a quick sanity check, running the map in the OP against some sample data:

import "sampledata"

sampledata.int() |> map(fn: (r) => ({ 
    _time: r._time,
    _value: r._value,
    _check_id: if exists r._check_id then r._check_id else "Unknown",
    _check_name: if exists r._check_name then r._check_name else "Unknown",
    _level: if exists r._level then r._level else "Unknown"
  }))

This ran without error for me in cloud. The error sounds like it comes from static analysis so I'd expect it to error consistently regardless of the data sent through the map call.
