Maybe try creating a bucket and then reading the region?

you'd need to check logs

WWalshy you'd need to check logs

I

IdkWhatever69•5/27/23, 6:51 PM

from where?

W

Walshy•5/27/23, 6:52 PM

tail or if you have logpush enabled then they'll be in your storage

WWalshy tail or if you have logpush enabled then they'll be in your storage

I

IdkWhatever69•5/27/23, 6:52 PM

logpushs are paid right?

W

Walshy•5/27/23, 6:53 PM

it requires a paid plan iirc but the feature itself isn't paid

I

oh nevermind but it's very cheap 10 mil included then only $0.05/mil (after filtering)

W

Walshy•5/27/23, 6:54 PM

best you'd get is tail then

W

Walshy•5/27/23, 6:55 PM

it'll fire again in 6 mins so start tailing now and wait 6 mins

WWalshy it'll fire again in 6 mins so start tailing now and wait 6 mins

I

so just

wrangler tail

right?

what's the code doing?

W

Walshy•5/27/23, 7:06 PM

do you make a request to a service or anything?

I

yes actually

so probably that service returned something unexpectedly

James•5/27/23, 7:10 PM

Yeah you're making a lot of assumptions about those requests always returning a 200, and always returning valid JSON

J

James•5/27/23, 7:10 PM

I'd guess one of them had a hiccup

J

James•5/27/23, 7:11 PM

If you wanted to make it more resilient,, make the request, check if OK, check if JSON, and then call

.json()

.json()

.json()

.json()

J

James•5/27/23, 7:11 PM

Depending on the service, I might also check the data is returns, in case there's a chance

properties.periods

properties.periods

properties.periods

properties.periods doesn't exist, for example.
