Bug: unable to serialize Map<String, Any> #96

Closed krisbitney closed 1 year ago

krisbitney commented 1 year ago

Version

Describe the bug I am trying to deserialize this map as Map<String, Any>

val env = mapOf(
    "provider" to listOf("https://ipfs.wrappers.io"),
    "fallbackProviders" to listOf("https://ipfs.io"),
    "retries" to mapOf("tryResolveUri" to 2, "getFile" to 2),
)

val encodedEnv = msgPackEncode(MsgPackDynamicSerializer, env)

I am getting the "End of Stream" exception thrown at line 31 of MsgPackDataBuffer.

See: https://github.com/esensar/kotlinx-serialization-msgpack/blob/main/serialization-msgpack/src/commonMain/kotlin/com.ensarsarajcic.kotlinx.serialization.msgpack/stream/MsgPackDataBuffer.kt#L31

Expected behavior I expected the map to serialize using the dynamic serializer

This is actually resolved by using msgPackEncode(MapSerializer(String.Serializer, MsgPackDynamicSerializer), env)
