Question

Hi there Can somebody tell me what can cause an issue when I receive unknown `enum` value from API and leads to error response As I can see apollo generates `safeValueOf rawValue String ` method in enum class alongside with ``` Auto generated constant for unknown enum values UNKNOWN UNKNOWN ``` value for unknown enums Also there is usage of this method in `operator fun invoke reader ResponseReader ` for entity that contains this enum Do I need to explicitly enable something to make this work so I apollo can parse unknown enum values to UNKNOWN

Hi What error are you getting I think unknown enum values should be map to `UNKNOWN` automatically

mbonnin · Answer

You can look into `sealedClassesForEnumMatching` if you want to read the rawValue of unknown enums

I just receive `Can t serialize value me roles 2 Invalid input for Enum MyEnum Unknown value NEW ENUM VALUE ` in `response response errors` where `response` is `ApolloResponse` accessed in ApolloRequestInterceptor

Oleksii Yerastov · Answer

so it is not mapping to `UNKNOWN` and just fails during mapping of response

mbonnin · Answer

It sounds like this happens while serializing arguments

mbonnin · Answer

Mmm or maybe your server doesn t like NEW ENUM VALUE

mbonnin · Answer

Yep more likely a server error

Oleksii Yerastov · Answer

It happens during parsing of response from server

Oleksii Yerastov · Answer

I receive array of enums with unknown value to client

Oleksii Yerastov · Answer

client 100 is not sending this enum value to server

mbonnin · Answer

I would expect a ApolloParseException for client parsing errors response errors should come from the server

mbonnin · Answer

Can you hook a proxy or httplogginginterceptor to rule that option out

Oleksii Yerastov · Answer

it s happening in multiplatform code so there is no httplogginginterceptor and I ll need your guidance for further investigation

mbonnin · Answer

I see I ll be at my computer in ~20min will dig more then

Oleksii Yerastov · Answer

thanks will be waiting pray

mbonnin · Answer

Is there any chance you can share your query

mbonnin · Answer

To debug this further a proxy would be quite useful this really looks like this error is coming from the server If a proxy is not an option you can customize the default HttpNetworkTransport by using expect actual Something like ```actual fun customApolloHttpNetworkTransport serverUrl String NetworkTransport = ApolloHttpNetworkTransport serverUrl = serverUrl headers = emptyMap httpCallFactory = OkHttpClient Builder addInterceptor HttpLoggingInterceptor apply level = Level BODY build httpMethod = <http HttpMethod Post|HttpMethod Post> ```

Oleksii Yerastov · Answer

Oh we found the reason and it is actually some internal code on backend persevere So sorry for bothering you without checking appropriately
