In case someone is facing 4xx errors on their images, you can try appending the query search params on the url on Line 69
Example:
Oldresponse = await fetch(`https://www.notion.so${url.pathname}`, { body: request.body, // must match 'Content-Type' header headers: request.headers, method: request.method, // *GET, POST, PUT, DELETE, etc. })
New
response = await fetch(`https://www.notion.so${url.pathname}${url.search}`, { body: request.body, // must match 'Content-Type' header headers: request.headers, method: request.method, // *GET, POST, PUT, DELETE, etc. })
amazing. thanks
Thanks, perfect work!
Try NotionDog if you have no custom domain and no money. 😉
I believe it's the easiest way to build simple, powerful websites with nothing but Notion.

Hey there, Really appreciate this script, I am struggling with changing it with how Notion has changed their public site link options. I've used the FruitionSite Script could anyone help with this?
Notion errors out with "Mismatch between origin and baseUrl (dev)." during the worker preview. Any thoughts?
Generate again the worker script from the fruition site and paste into the Cloudflare worker script.
It worked for me.
Hello,
I am facing a problem.
I would like to redirect the domain I have acquired on google domains to a notion page.
I have set up the worker, a A record, and the DNS but somehow it does not redict it.
I have an : ERR_NAME_NOT_RESOLVED error
telling me : impossible to find IP adresse
Do you have any chere it can come from ?
Cheers,
