When i call both endpoins and my serializer looks like this (check order )

register(CocktailIngredientMatrix.serializer().list)
register(Ingredient.serializer().list)

I get error from /cocktailIngredientMatrix endpoint
RESPONSE <http://10.0.2.2:8080/cocktailIngredientMatrix> failed with exception: kotlinx.serialization.json.JsonDecodingException: Invalid JSON at 23: Encountered an unknown key cocktailID

When i change thh order to :

register(Ingredient.serializer().list)
 register(CocktailIngredientMatrix.serializer().list)

I get following error :
RESPONSE <http://10.0.2.2:8080/ingredients> failed with exception: kotlinx.serialization.json.JsonDecodingException: Invalid JSON at 41: Encountered an unknown key name

Hi @martin.petrulak, could you check the content of json?

[martin.petrulak]

Hey sure, i mean , code works if i have registered only one resializer.

So if i call /ingredients and only Ingredient serializer is registered code works.

Same goes for /cocktailIngredientMatrix , it works ,if i have registered only CocktailIngredientMatrix serializer.

In scenario when i want to hit both enpoints -> i need both serializers to be registered, one of them throw an exception.

Wierd thing is that when i change the order of how i register the serializer, the one that did not worked works, and the one that worked doesnt work

Yep, it looks like an issue. We deprecated registerSerializer because of typeOf
