Hi, I'm having trouble using EitherCallAdapterFactory when minifying. Do I have to add any extra R8/Proguard rules?

[Javi Chaqués]

@POST("API URL")
    suspend fun signIn(
        @Body request: SignInApiRequest,
    ): Either<CallError, SimpleCallApiResponse<SignInApiResponse>>

Doesn't seem like a proguard issue. Looks like the extra generic (SimpleApiResponse) is the issue

[stojan]

AFIK it doesn't need extra rules other than whatever retrofit requires

[Javi Chaqués]

@Serializable
data class SimpleCallApiResponse<T>(
    @SerialName("data") val data: T,
)

[Javi Chaqués]

@Serializable
data class SignInApiResponse(
    @SerialName("accessToken") val accessToken: String,
    @SerialName("refreshToken") val refreshToken: String,
)

[Javi Chaqués]

if I remove Either from response, it's work correctly

[stojan]

Could you try the other way, creating a specific type (without generics) for the response

[Javi Chaqués]

I have the same problem with this response

@Serializable
data class TestResponse(
    @SerialName("data") val data: SignInApiResponse,
)

[Javi Chaqués]

it's working if i add this rule

-keep class arrow.core.Either** {*;}

hm... that's strange.... the adapter doesn't use reflection AFIK
