I am getting 403 when trying to fetch /manifest.webmanifest

I am using PWA in my angular app to recognize when there is a new version deployed. My problem is that vercel blocks the access to the file manifest.webmanifest, so when i am trying to fetch from https://www.MY_URL/manifest.webmanifest i get blocked by vercel with status code 403.
I added a rule in the firewall, but it did not help.

What am i missing? How can i allow access to this file?

Hi @focusprojectsmanagem, welcome to the Vercel Community!

Can you check your firewall logs to see why these requests are getting blocked?

Eventually i was able to figure it out - this was happening because of the active attack mode.
I saw that it is not recommended to keep it on, but i did not understand why

Thanks for sharing it here.

The attack challenge mode meant to be used only for active DDoS attacks. The reason being the enhanced and more strict rules being applied, which can block any suspicious activities like downloading a file. You can read more on our Attack Challenge Mode docs.

Let me know if you need more help.
