emmm, It is an environment variable and is not part of the settings.

So you need to specify this environment variable in advance when you start databend.

RUST_BACKTRACE=1 make run

or

export RUST_BACKTRACE=1
databend-query

After I set export RUST_BACKTRACE=1, and restarted databend, I got the following error, I don't understand

ERROR 1105 (HY000): Code: 1104, displayText = called `Result::unwrap()` on an `Err` value: Code: 1010, displayText = Can't construct type from Int64(Int64) and Float64(Float64).
