Let me get around to that after we resolve the other incident first

Hi all. I'm building a webhook worker to translate between two cloud services. I've set up everything and tested, but not getting any POSTs from the source service. It's Peplink's IC2 service. https://incontrol2.peplink.com/ They claim they are successfully sending the HTTP POSTs, but I have nothing in the logs. I'm even debugging to KV and seeing nothing. They claim that CloudFlare is blocking IC2 requests. I don't think I have any bot filters or firewall running. Any ideas?

Well.. I assume you have done the "Test service manually with curl or postman".. and double checked the URLs?

Erwin•5/6/22, 3:59 AM

And what do they mean by successfully? Do they get back a 200? Do you have overlapping routes, where something goes to another worker than you think it does?

Tbh I am a little surprised there hasn't been a massive push by the teams for Albert to ban me from Discord, seeing how many incidents I have brought them from here

You can’t return within the promise (since it’s async). You’d want to await that and then handle.

Erwin•5/6/22, 4:29 AM

What is not having what? And where does myHeaders come from? And what happens in handleResponse?

Erwin•5/6/22, 4:53 AM

And what is the problem exactly?

XXiNiHa Yeah it must be chunked to get advantages from it

XiNiHaOP•5/6/22, 7:12 AM

New fact here - Chrome just renders the page as they arrive in the stream, while Firefox and Safari requires Transfer-Encoding: chunkedTransfer-Encoding: chunked (they otherwise block rendering until the stream ends)

XiNiHaOP•5/6/22, 7:12 AM

Maybe that's the reason why the problem was not spotted - since most people use Chrome

I am pretty sure we set the

in some cases, just need to figure out which cases it does and does not do it..

Google gives me “Spring Boot” and no results for Bootspring - what is it?

kian•5/6/22, 7:50 AM

Yeah but can’t give an answer if it’ll work on Workers without knowing what it is

kian•5/6/22, 7:56 AM

JWS is JSON Web Signature - a type of web token.

kian•5/6/22, 7:56 AM

Spring Boot is Java from the looks, not JavaScript

kian•5/6/22, 7:56 AM

Workers only run JavaScript or WebAssembly - any other languages will need to compile (with a translation layer) into JS

kian•5/6/22, 8:02 AM

It entirely depends if it can be turned into JavaScript - if it is specifically Java, then it won’t work on Workers.

There’s a lot more to consider when planning a move as well - Workers can’t open TCP connections to external databases so if you have a database, it’ll need a HTTP connector in-front of it.

Workers are stateless and invoked on a per-request basis so you’ll need to use something like Workers KV, or an external database, to manage anything that you need to refer to between requests.

kian•5/6/22, 8:03 AM

It’s a lot different to Heroku which seems to to be container based and supports plenty of languages - Workers is all about V8 isolates and JavaScript/WebAssembly
