Data class with default param is not serialized

Question

Data class with default param is not serialized

sapuglha opened this issue 4 years ago · 2 comments

Serialization of data classes where properties contain default params are not being serialized, since the recent upgrade to 1.0.0 (from 1.0.0-RC) and this lib from 0.7.0 to 0.8.0.

I added a new test to replicate the problem. #37

I'm not sure whether a change in this lib or Kotlin Serialization is the reason for that.

This is caused by the fact that in 1.0.0 the default behavior was changed, see changelog. Now kotlinx.serialization's Json does not serialize default values by default. To change that, you can add encodeDefaults = true to your Json {} configuration block.

Thanks @sandwwraith, I should have checked the changelog first.
