Hi everyone, I’m using ktor and dynamodb for my backend project. I’m trying to fetch data from db using the below piece of code:
Copy code
getDynamoDbClient().use { ddb ->
                return@use ddb.getItem(dbRequest)
            }
Upon running this, I’m getting
java.lang.IncompatibleClassChangeError: Found interface kotlin.time.TimeMark, but class was expected
error. I’m doing it as it’s shown in https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/kotlin/services/dynamodb/src/main/kotlin/com/kotlin/dynamodb/GetItem.kt. Am I doing anything wrong? Kotlin version: 1.7.0, Ktor version: 2.0.2, aws version: 0.16.0 TIA

I think it's a breaking change. Saw something similar in kotest when I tried to move to Kotlin 1.7.

@itzik kasovitch Yeah, just saw that issue. Anyway, I’ve created an issue for aws here

The release notes for 1.7.0 note that time related classes are now inline classes to improve performance. It is interesting that the error notes it as an interface, however.

I can’t believe that the time apis are still marked as @ExperimentalTime (since 1.3). This needs to become stable at some point.
