Intent Kotlin receiving null value

Question

I have the following Intent of an Activity:

val intent = Intent(this, FormCadastroUsuario::class.java)
        intent.putExtra("email", email)
        startActivity(intent)

And to receive in another Activity, I have the following code:

val email = intent.getStringExtra("email").toString()

However, this variable is always "coming" with the null value. What can I do to receive with the correct value of the original Activity?
