Requests suddenly having no headers

Hello,

I'm working on some functions that read a specific header, and I'm suddenly realizing that no headers are getting to my code. This was working fine earlier, and it's just suddenly not and I'm not sure what has changed

I should note I'm using SvelteKit, but afaik SvelteKit doesnt change the actual request object in any way

Here is the code I have in my

hooks.server.ts

hooks.server.ts

that is working fine in dev and was working fine on CF too until about 2 hours ago

        const data = {
            site: "[redacted]",
            ua: event.request.headers.get("User-Agent"),
            url: event.url,
            id
        };
        if(!data.ua) {
            console.log({headers: event.request.headers.keys()})
        }

        const data = {
            site: "[redacted]",
            ua: event.request.headers.get("User-Agent"),
            url: event.url,
            id
        };
        if(!data.ua) {
            console.log({headers: event.request.headers.keys()})
        }

Then this appears in the tail:

        {
          "headers": {}
        }

        {
          "headers": {}
        }

And, of course, data.ua is null. I find it very odd that this was all working fine, then suddenly it's not.

Any ideas about what might be causing this?
