Hi, i am trying to implement supabase in my existing proyect, and i want to make a query to test that all works fine, but it throws me an exeception when i execute the program, it gives me this error:

`E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.example, PID: 23243

also the class has de @serializable in top of the data class. and i imported all the dependencies and the plugins.

Can you share the whole class? And also you are sure that you have installed the serialization plugin?

[Ramboo018]

no the "s" is in upper case and the IDE is not showing any warning, all seems right

[jan-tennert]

Does serialization work manually? Try:

Json.decodeFromString<PilotoGet>("{}")

To see if that serializer works (will fail as this is not valid input).

[Ramboo018]

it throws the same error

"kotlinx.serialization.SerializationException: Serializer for class 'PilotoGet' is not found.
Please ensure that class is marked as '@serializable' and that the serialization compiler plugin is applied."

[jan-tennert]

Okay, without a repo or another way to reproduce the problem, I can hardly know what's wrong. You can maybe ask in the kotlin slack under #serialization. Just to be sure, the kotlinx serialization plugin version is the same as kotlin?

[Ramboo018]

ok, that was the problem, kotlin by default put me the version in 1.9.0-Beta and the serialization plugin was on the 1.8.21. I didnt know that you need both on the same version, i updated both to 1.8.22 and now it works perfectly fine, thanks for you help <3
