bash: script running in pm2 unable to access file descriptors files at /dev/fd/

I have script script.sh:

#!/usr/bin/env bash

# pm2 seems to always run in bash regardless of #!
echo "running in $(readlink -f /proc/$$/exe)"

# Redirect to both stdout(1) and stderr(2)
echo "hello" | tee /dev/fd/2

I am running it with pm2 start script.sh I can see logs at pm2 logs like so:

tee: /dev/fd/2: No such device or address

Which means script is unable to access /dev/fd. Although this problem doesn't happen when directly running in a bash terminal. --- - About pm2: https://pm2.keymetrics.io/docs/usage/quick-start/ - Previous discussion: https://stackoverflow.com/questions/78885319/bash-redirecting-to-multiple-file-descriptors - For reference : https://unix.stackexchange.com/questions/26926/file-descriptors-and-dev-fd
