Cannot execute docker exec command on WSL2 using open3

Im having issues running a docker exec command on WSL2 using open3. To reproduce I wrote this simple script:

require 'open3'

command = "docker exec -i <CONTAINER_NAME> ls /"
puts "Running #{command}"

stdout, stderr, status = Open3.capture3(command)

puts "STDOUT: #{stdout}"
puts "STDERR: #{stderr}"
puts "STATUS: #{status.exitstatus}"

Running in WSL2 this results in output:

STDOUT:
STDERR:
STATUS: 0

If I run this script in git bash instead I get output:

Running docker exec -i service-build-instance ls /
STDOUT: bin
boot
build
dev
etc
home
lib
lib64
media
mnt
opt
proc
root
run
sbin
srv
sys
tmp
usr
var
STDERR:
STATUS: 0

Anyone who may know what is going on here?

Start with the reproduction script and its Open3.capture3 call, then compare the command's behavior in WSL2 and Git Bash. Determine whether the empty stdout with exit status 0 comes from Open3, Docker, or the environment; done means identifying the cause and a supported next step or documenting that the issue is external to Open3.
