============= End of log =============

Steps to reproduce

1. Add pre-launch script:

#!/bin/bash


# Define source and destination file paths from command-line arguments

DEST_DIR="$DEST_DIR/$(basename "$SOURCE_DIR")"
env


# Check if both arguments are provided

if [ -z "$SOURCE_DIR" ] || [ -z "$DEST_DIR" ]; then

  echo "Usage: $0 <source_directory> <destination_directory>\nSOURCE_DIR: $SOURCE_DIR\nDEST_DIR: $DEST_DIR"

  exit 1

fi



# Check if the source directory exists

if [ ! -d "$SOURCE_DIR" ]; then

  echo "Source directory $SOURCE_DIR does not exist."

  exit 1

fi



# Check if the destination directory exists

if [ -d "$DEST_DIR" ]; then

  echo "Destination directory exists. Creating a backup: $DEST_DIR.bak"

  # Remove the existing backup directory if it's there

  if [ -d "$DEST_DIR.bak" ]; then

    echo "Removing existing backup directory $DEST_DIR.bak"

    rm -rf "$DEST_DIR.bak"

    if [ $? -ne 0 ]; then

      echo "Failed to remove existing backup. Exiting."

      exit 1

    fi

  fi

  # Move the existing destination directory to backup

  mv "$DEST_DIR" "$DEST_DIR.bak"

  if [ $? -ne 0 ]; then

    echo "Failed to create backup. Exiting."

    exit 1

  fi

fi





# Create the destination directory if it does not exist

if [ ! -d "$DEST_DIR" ]; then

  echo "Destination directory does not exist. Creating $DEST_DIR..."

  mkdir -p "$DEST_DIR"

  if [ $? -ne 0 ]; then

    echo "Failed to create destination directory. Exiting."

    exit 1

  fi

fi



# Copy the source directory to the destination, overwriting if needed

echo "Copying contents from $SOURCE_DIR to $DEST_DIR..."

cp -r "$SOURCE_DIR"/* "$DEST_DIR"

if [ $? -eq 0 ]; then

  echo "Contents copied successfully."

else

  echo "Failed to copy contents. Exiting."

  exit 1

fi



# Ensure the operation is completed before exiting

sync

echo "Syncing completed."



exit 0

2. Add custom environment variables
3. Nothing turns up in log besides Heroic's

Expected behavior

Custom environment variables to be accessible to launch scripts
