conda export env from bash script

Question

I came up with the following bash script to export my conda-env to a file.

run.sh

#!/usr/bin/bash
while [[ $# -gt 0 ]]; do
option=$1
case "$option" in
    -e|--export)
        conda env export -n myenv | grep -v "^prefix: " > ../setup/env.yaml
        shift
        ;;
        esac
done

the line conda env export -n myenv | grep -v "^prefix: " > ../setup/env.yaml works as expected when executed in command line. But on executing ./run.sh -e, the env.yaml looks like,

name: myenv
channels:
  - defaults

Seeking help to fix this. Thanks.

Edit: already tried the string and eval method from the link (https://stephencowchau.medium.com/simple-bash-script-to-export-all-conda-virtual-environments-2e337cd9480), which also yields the same result as my script.

Edit2: This seems to work in Linux machines. But not working in WSL in windows.

Adding the following lines in the start of script fixed the issue

CONDA_PATH=$(conda info | grep -i 'base environment' | awk '{print $4}')
source $CONDA_PATH/etc/profile.d/conda.sh
