Why serialization can't to serialize collection with nullable items in ProtoBuf?

@Serializable
data class MyData(val myList: List<String?>)

I found out, that serializer set property nullableMode = NotNull , but it is set for list, items in list can be nullable

[ephemient]

for a non-repeated property, "null" is "missing", but a list is represented by a repeated tag. how do you expect to repeat a missing value in protobuf?

hm

[ephemient]

if you wrote

@Serializable
data class NullableString(val value: String? = null)
@Serializable
data class MyData(val myList: List<NullableString>)

it would work but have a different representation, of course

got it, thank you, I will find better workaround
