Subprocess launched inside a chroot created on a codespace with debootstrap fail with /dev/fd/62: No such file or directory

My goal is to standup a chroot with the basic Unix tool-set (bash, cp, touch, cat, etc) and any necessary dependencies need to run apt get inside a codespace. Using debootstrap gets me close. The basic tools are installed and I can run apt get. The problem is subprocess do not work. I expect the last line to print "test" but actually I get an error saying that the subprocess' file handle is no good. I would have thought the vanilla debootstrap environment would be sufficiently cooked so that subprocess work, but that does not seem to be the case. Is there a switch I can pass?

$ sudo apt-get install -y binutils debootstrap
$ cd /home/codespace
$ CHROOT=/home/codespace/chroot
$ mkdir -p "${CHROOT}"
$ sudo debootstrap stable "${CHROOT}" http://deb.debian.org/debian/ 
$ sudo chroot "${CHROOT}"
$ cat < <(echo test)
bash: /dev/fd/63: No such file or directory

To reproduce, - sign up for codespaces beta [here](https://github.com/features/codespaces/signup) . - fire up a codespace for [this project](https://github.com/kingces95/chroot-mounts) , open a bash shell (ctrl+`). - run the above. This also reproduces outside of codespace so any Ubuntu environment will probably yield similar results.
