Serializer for class 'ObjectId' is not found when pass a data object in a response in Ktor server

Hi everyone,
As described in the title, whether it is a kotlin-driver’s bug or I missed somewhere in my code?

[Tan_Tai_Le_Kim]

I solved my problem. MongoDB Driver is great. You have a lot of customizations to play around with it.

How did you solve your issue ?

[Tan_Tai_Le_Kim]

I overrode ObjectId field with Custom Serializers as the attached picture. You can follow document link to get full customization for other types.

I went throught the documenrtation.
Got it Thank You.

I am not able to get it working seamlessly with the custom Serializer that i have written, could either you share the Custom serializer for ObjectId

[Tan_Tai_Le_Kim]

The problem here is kotlinx.serialization doesn’t know BSON types. So, you need to transform these types to JSON types. This is my Custom serializer for ObjectId, as you wish.
