The PNG loop catches wkhtmltoimage/convert failures and only logs an error, but after the loop it always prints a success banner and exits normally. That means in environments where wkhtmltoimage exists but fails (e.g., missing X/Qt libs, bad HTML, or permission issues), the script still claims PNGs were generated and lists file paths even though they may not exist, which undermines automated PR screenshot expectations. Consider tracking failures and exiting non‑zero or suppressing the success message when any render fails.
Useful? React with 👍 / 👎.
