🐛 Bug Report — Response.redirect() doesn't throw error on too large header

[Frigyes06]

I was working on a page that would take an arbitrary text input from a user and redirect them to a domain with the location header set to the data input. However, this call generates an Internal error when called with a location that exceeds the limit of the location header. It dies not throw an error on the JS/TS side which could be handled.

Example code:

export default {
	async fetch(request, env, ctx): Promise<Response> {
		var redirectUrl = String(new URL(request.url + "*long data, like entire bee movie script here*"))
		try {
			return Response.redirect(redirectUrl)
		} catch(err) {
			console.log(err)
		}
	},
} satisfies ExportedHandler<Env>;

Expected behavior:

The Response.redirect() throws an error which is handled (in this case logged to console), and the program continues

Current behavior:

The process throws an internal error:

Error: internal error

Error when run on CF Workers:

I might be totally in the wrong here, but I would expect the function to throw at least a generic error instead of crashing and burning.

Please let me know if I'm dumb and/or if you need more details.
