You could, but you can’t actually construct it until you have received a request

Just have a variable that can be an OpenAI API client, but by default is null. Then, whenever you need it, use the variable if present, otherwise initialize it first

Those kind of error pages usually appear if your browser is making a request that isn't valid according to the HTTP specification.

I

Isaac McFadyen•11/26/23, 5:06 PM

For example, if you send a body in a GET request then you might get that. Or if you send a header name that isn't valid. Or any number of other things really.

I

Isaac McFadyen•11/26/23, 5:06 PM

Take a look and make sure that the POST request you're making is valid and looks fine syntactically

There is any good project example for workers and D1 to start from ? Like with multiples APIs / files

D

dave•11/26/23, 7:47 PM

Question, for those of you who have had their Workers DDoS'd, how was the experience? Does CF do a decent job of blocking requests before they hit the Workers?

D

dave•11/26/23, 7:51 PM

nice. I was debating if I should use Google Cloud Run without Workers, but I think it makes sense to always use Workers in front.

D

dave•11/26/23, 7:51 PM

it does increased the cost from $0.20/million requests to $0.50/million requests when stacking a Worker on top, but the benefit of DDoS protection makes it nice.

You can even block by header value on, so if they did have a valid authentication token somehow they would still get blocked.

Is middleware only available for Cloudflare Pages and not Workers?

J

James•11/26/23, 9:41 PM

Middleware is a thing for Functions since they have file-based routing, and the concept of Middleware makes a lot of sense there for handling auth, etc.

J

James•11/26/23, 9:41 PM

Many popular routers and frameworks for Workers also support Middleware though, such as https://hono.dev/

My cron worker job got killed for exceeding time (32,000 ms). Is there a way to increase that number?

F

Fun Miles•11/27/23, 12:15 AM

The docs, under CPU time say

When the schedule interval is more than 1 hour, a scheduled Worker may run for up to 15 minutes.

When the schedule interval is more than 1 hour, a scheduled Worker may run for up to 15 minutes.

I

Isaac McFadyen•11/27/23, 2:37 AM

It's unrelated to Wrangler. That error page is something you'd receive before the request even hits the Worker, nothing you're doing in your Worker should trigger that.

Its not an SSL error or an error in the workers code. Cloudflare does some basic validation on requests and if it does not pass the basic validation you get the generic 403 error. That generic 403 error means it never even attempted to forward the request to your worker or to an origin

Hi all. Say I have a zone called

foo.bar.com

foo.bar.com

and a workers route for

*.foo.bar.com/*

*.foo.bar.com/*

that goes to my worker, plus a proxied DNS record for

*.foo.bar.com

*.foo.bar.com

. All that works fine. Then we decide to create a zone for

bar.com

bar.com

and migrate off

foo.bar.com

foo.bar.com

into this zone. Added the same proxied DNS record to this

bar.com

bar.com

zone and the same workers route. Issue we're seeing is that the requests seem to go straight to the origin server but they don't seem to be hitting the worker at all.

Any ideas/thoughts?

Correction: it seems to break whenever I remove the workers route from the old

foo.bar.com

foo.bar.com

zone. I want the new

bar.com

bar.com

to process these requests, not the old zone

What is the CPU limit accounting when using a bound worker with the new billing system? Does the worker called with fetch get counted as part of the caller's CPU usage, or does it get its own limit?

F

Fun Miles•11/28/23, 1:46 PM

If it were called via the network, it would get its own limit and the caller time would pause while awaiting for the result of the fetch, right? Is it similar for a bound worker call?
