logpushs are paid right?

W

WalshyOP•5/27/23, 6:53 PM

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

this project is for public service

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

best you'd get is tail then

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

do you make a request to a service or anything?

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.
