Watch out for

Instagram has strict image dimension requirements so validate aspect ratios before uploading to avoid rejection errors.
The webhook payload might contain missing or malformed URLs, add a check to skip invalid items gracefully.
Rate limits on the Instagram API can block rapid uploads, implement a small delay between child container creations.
Slack notifications may fail if the channel ID is incorrect, verify the target channel exists before sending messages.
