Any reason why Apollo client ( v3.7.4) throws ApolloNetworkException when response code is 401

[mbonnin]

What would you expect instead?

[Parijat Shah]

I could handle it or AuthException

[mbonnin]

i'd recommend you handle this at the HttpInterceptor level

[Parijat Shah]

I just wanted to understand the rational. I am already working with it.

[mbonnin]

This way you can retry transparently

[Parijat Shah]

That make sense.

[mbonnin]

All exceptions inherit from ApolloExcption so that it's easier to know what can happen

[mbonnin]

I'm not even sure there's a MPP AuthException?

[Parijat Shah]

There isn't . I meant something on those lines .. ApolloAuthException

[mbonnin]

Some servers handle auth at the GraphQl layer

[mbonnin]

There's no concept of Authentication in GraphQL, it's a HTTP thing really

[mbonnin]

It's all server dependant

[Parijat Shah]

I 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

[mbonnin]

Exactly!

[mbonnin]

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)

[mbonnin]

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

[Parijat Shah]

Yes. I am going to handle at Http level. Thank you for your inputs Martin.

[mbonnin]

Sure thing!
