I have a multiplatform project and i am using firestore.

I have this error after i installed version 1.8.1 and i want to use Timestamp.

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath: class dev.gitlive.firebase.firestore.TimestampSerializer, unresolved supertypes: dev.gitlive.firebase.SpecialValueSerializer.

this is my build.gradle from the shared project

`plugins { kotlin("multiplatform") kotlin("native.cocoapods") id("com.android.library") kotlin("plugin.serialization") id("com.rickclephas.kmp.nativecoroutines") }

kotlin.sourceSets.all { languageSettings.optIn("kotlin.experimental.ExperimentalObjCName") }

kotlin { android { compilations.all { kotlinOptions { jvmTarget = "1.8" } } } iosX64() iosArm64() iosSimulatorArm64()

    version = "1.0"
    ios.deploymentTarget = "15.0"
    podfile = project.file("../TabookIos/Podfile")
    framework {
        baseName = "shared"
        isStatic = true

        }
    }
}

}

android { namespace = "" compileSdk = 33 defaultConfig { minSdk = 28 targetSdk = 33 } }

`

How can i solve this problem?

[Michona]

One solution is to add dependency to dev.gitlive:firebase-common:1.8.1 in your commonMain, so that the SpecialValueSerializer can be resolved.

Hope that helps.

I believe this has been fixed in 1.9.0 - please reopen if something is missing
