java.lang.NoClassDefFoundError: java.time.LocalDateTime

I am using Zendesk SDK following this getting started guide:

version: zendesk.messaging:messaging-android:2.17.0

It could not resolve class java.time.LocalDateTime so I get following error:

On the internet somebody mentions it requires minSdkVersion of 26, but Zendesk requires 21. how would I solve this problem? Here is stackoverflow question

If i test on Android 7 which is Level 25 then what should i do? If minimum is 26 why is requirement 21?

My Settings in gradle:

android {

 compileSdkVersion 34

 // buildToolsVersion "32.0.0"

 // ndkVersion "

 defaultConfig {

 minSdkVersion 21

 targetSdkVersion 34

 // Version Information

 versionCode 1

 versionName "1.0.0"




 generatedDensities = []

 }

 aaptOptions {

 additionalParameters "--no-version-vectors"

 }

 compileOptions {

 sourceCompatibility = JavaVersion.VERSION_1_8

 targetCompatibility = JavaVersion.VERSION_1_8

 }

}
