I have the following class:

data class Person(
  // others attributes
  val maritalStatus: MaritalStatus,
  val gender: Gender
) : BaseEntity()

abstract class PersonBaseTable(schema: String) : Table("$schema.person") {
  // others attributes
  val maritalStatus = enumerationByName("marital_status", 15, MaritalStatus::class)
  val gender = enumerationByName("gender", 15, Gender::class)
  override val primaryKey: PrimaryKey = PrimaryKey(id, name = "person_id_uindex")
}

fun personTable(schema: String): PersonBaseTable = object : PersonBaseTable(schema) {}

and:

enum class MaritalStatus {
  Married,
  Single,
  Divorced,
  StableUnion,
  Widower,
  Uninformed
}

enum class Gender {
  Male,
  Female,
  Uninformed
}

my sql file (I'm using postgresql)

CREATE TYPE marital_status_enum AS ENUM ( 'Married','Single','Divorced','StableUnion','Widower','Uninformed');
CREATE TYPE gender_enum AS ENUM ( 'Male','Female','Uninformed');

CREATE TABLE IF NOT EXISTS rjdesenvolvimento.person
(
   //others columns
    marital_status marital_status_enum not null,
    gender         gender_enum
);

and:

entity.person?.let {
  personTable(schema).insert { personTable ->
    personTable[maritalStatus] = it.maritalStatus
    personTable[gender] = it.gender
  }

But I am getting the following error.

org.jetbrains.exposed.exceptions.ExposedSQLException: org.postgresql.util.PSQLException: ERROR: column "marital_status" is of type marital_status_enum but expression is of type character varying
  Hint: You will need to rewrite or cast the expression.
