Troubleshooting

Token expired

Facebook Page tokens can expire. Regenerate from Graph API Explorer.

Missing permissions

Ensure your app has pages_manage_posts permission and you're using a Page token (not User token).

Image not generated

Check if your AI gateway supports image generation via chat completions. Some models return images in message.images[] array.

Connection error in wrangler

Cloudflare Workers can't access localhost. Use production gateway URL in .dev.vars.
