Running Custom Bash Script Works in Terminal But Not RayCast

I'm writing a Raycast bash script that converts the most recent Screen Recording into a Gif using this tool. The script is below. The line: ffmpeg -i "$recent_file" -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > out.gif works properly when run in Terminal. Unfortunately, it doesn't output out.mov when run in Raycast, despite the fullOutput of Raycast showing it completes as intended (see screenshot). Is there some kind of setting required in Raycast to allow the use of these command-line tools?

#!/bin/bash

# Required parameters:
# @raycast.schemaVersion 1
# @raycast.title Gif Most Recent Screen Recording
# @raycast.mode fullOutput

# Optional parameters:
# @raycast.icon 🤖

# Documentation:
# @raycast.author willbeing
# @raycast.authorURL https://raycast.com/willbeing

directory="/Users/willbeing/Desktop/Screenshots"  # Replace with your desired directory

# Check if the directory exists
if [ ! -d "$directory" ]; then
  echo "Directory does not exist."
  exit 1
fi

# Check if the directory exists
if [ ! -d "$directory" ]; then
  echo "Directory does not exist."
  exit 1
fi

# Retrieve the most recent .mov file
recent_file=$(ls -t "$directory"/*.mov 2>/dev/null | head -n 1)

# Output the most recent .mov file
if [ -n "$recent_file" ]; then
  ffmpeg -i "$recent_file" -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > out.gif
else
  echo "No .mov files found in the directory."
fi

Script worked as intended. Thanks to @CharlesDuffy I learned about some valuable debugging tools...

• Enable Retrace: PS4=':$LINENO+'; set -x
• Redirect stderr to a known location: exec 2>/tmp/myscript.$$.log
• Compare environment variables between the two environments: you can use declare -p to dump pretty much everything or env for just environment.

...and of course to review the obvious, such as check the directory of the output file. In the raycast case it was the scripts directory (where I was not looking) 🤦‍♂️
