02/22/2023, 11:02 PMWhat would you expect instead?
p
Parijat Shah
02/22/2023, 11:07 PMI could handle it or AuthException
m
mbonnin
02/22/2023, 11:08 PMi'd recommend you handle this at the HttpInterceptor level

02/22/2023, 11:08 PMI just wanted to understand the rational. I am already working with it.

02/22/2023, 11:08 PMThis way you can retry transparently

02/22/2023, 11:08 PMThat make sense.

02/22/2023, 11:09 PMAll exceptions inherit from ApolloExcption so that it's easier to know what can happen
I'm not even sure there's a MPP AuthException?

02/22/2023, 11:11 PMThere isn't . I meant something on those lines .. ApolloAuthException

02/22/2023, 11:11 PMSome servers handle auth at the GraphQl layer
There's no concept of Authentication in GraphQL, it's a HTTP thing really
It's all server dependant

02/22/2023, 11:14 PMI agree. I guess only way to propagate 401 is throwing exception and it makes more sense to handle it at HttpInterceptor level since it is actually HTTP thing
m
mbonnin
02/22/2023, 11:15 PMExactly!
I think if you really want to you should be able to get the HTTP code from the ApolloNetworkException (there should be a ApolloHttpException somewhere in 'cause' or so that contains the status code)
Not 100% sure about the details as I'm on mobile right now but in all cases, HTTP is the good place to handle this

02/22/2023, 11:19 PMYes. I am going to handle at Http level. Thank you for your inputs Martin.
