Has anyone successfully set up a tail worker?

Seems like several people (including myself) are having trouble getting it working. The configuration is set on the producing worker in the settings -> variables, but the tail worker doesn't report that it is tailing any worker. However i was seeing successful "requests" on the metrics page... but it doesn't seem to do anything. No console.logs. nothing.

You can't tail a Tail Worker, if that's what you're trying to do.

Hi! PM for Tail Workers here -- sounds like you're seeing invocations on your tail worker but no messages being sent? Is that a correct understanding

It looks like it but the tail() handler isn't being executed. I just was seeing activity in the metrics dashboard. I have a console log and a kv put in the handler but see no logs or kv data

@wellcaffeinated do you have a solution for this problem?

not working to me also

I attached a simple worker to another with tail worker but tail function is never executed.

If you have any advice @tanushree I appreciate it!

Unfortunately still not working for me too

What is your Tail Worker doing?

pigri•7/25/23, 6:54 PM

console.log(events);

pigri•7/25/23, 6:54 PM

that's all

Kkian You can't tail a Tail Worker, if that's what you're trying to do.

kian•7/25/23, 6:55 PM

You'll never see them since you can't view the logs of a Tail Worker

pigri•7/25/23, 7:03 PM

okay i understand

pigri•7/25/23, 7:04 PM

that's little bit hard to debugging or developing tail worker

pigri•7/25/23, 7:04 PM

tail working bindig is it working in local?

kian•7/25/23, 7:05 PM

Not that I'm aware of

kian•7/25/23, 7:05 PM

iirc there's also a bug (which I've experienced) where you need to republish the Worker you're tailing whenever you publish a new revision of your Tail Worker, otherwise it still runs the old code

kian•7/25/23, 7:06 PM

They're pretty rough to use

pigri•7/25/23, 7:08 PM

hmm... I need to drop my original idea

kian•7/25/23, 7:08 PM

If it works for you, Logpush for Workers is much more stable currently

pigri•7/25/23, 7:09 PM

yeah logpush working fine

pigri•7/25/23, 7:10 PM

my original idea is i have an analytics service currently use a http endpoint but have latency here

pigri•7/25/23, 7:10 PM

that's why I want to use the tail worker

kian•7/25/23, 7:11 PM

If you're unlikely to make any changes to the Tail Worker, once it's working, there isn't any big issues with it

kian•7/25/23, 7:11 PM

It's just the development stage which is rough

pigri•7/25/23, 7:11 PM

yeah it's a little bit blackbox

pigri•7/25/23, 7:28 PM

thanks for the help @kiannh

I'm not tailing a tail worker, I'm setting a kv entry but it never runs
