I am passing data to some fragment in bundle and while receiving it throws the exception "java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.b.h.b, parameter schoolName"

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.b.h.b, parameter schoolName

Hey, could you please send the ProfileData class? I'll take a look

[grandstaish]

@Anmol92verma are you able to post that class, or alternatively some other code that demonstrates the issue?

Hello.

I have the same problem. I see this error when I'm building the release project with proguard.

Have you got a solution?

[grandstaish]

@Slik1002 you won't need any special proguard rules for this library. It sounds as though you have a kotlin model, but it's being instantiated incorrectly (probably through the usage of Gson or Moshi). Just a guess!

If that is the case, then your model object was instantiated with a null value in a non-nullable field, then that null value got Parcelled, then my library tried to unparcel it. At that point kotlin throws an exception because that field should never have been null in the first place.
