I am trying to migrate my application to Axon 4.0 with Axon server. Here is my code.
data class CreateTravelProductCommand(
@TargetAggregateIdentifier val id: String,
val productCreator: String
)
val id: String = ObjectId.get().toString()
val command = CreateTravelProductCommand(id=id, productCreator=request.creator)
commandGateway.sendAndWait(command)
But I got this error with my command.

Edit:
I just found out that if you keep the class in the same project, it is ok.
The problem is when you import the class from another project (Which used to work prior to axon server)
For example:
My project has dependencies of another project called api.
dependencies {
compile project(':api')
}
If the class is declared in the api project, axon server library will throw error that it cannot find routing key. But if the class is declared in the main project it self, it works as expected. I think I should file this issue on github.
