Can't insert into MySQL table without auto index

I’m trying to insert a simple row into a table:

                        transaction {
                            GuildPrefixTable.insert {
                                it[id]._value = event.guild.idLong
                                it[prefix] = ""//event.guild.idLong
                            }
                        }

it doesn’t throw an error but it never actually inserts anything (even if I remove the line setting it[id]._value. The table is defined as:

object GuildPrefixTable : LongIdTable("guild_prefix") {
    val prefix = text("prefix")
}
class GuildPrefix(id: EntityID<Long>) : LongEntity(id) {
    companion object : LongEntityClass<GuildPrefix>(GuildPrefixTable)
    var prefix by GuildPrefixTable.prefix
}

and in MySQL, the table is just id (bigint(20), not automatic primary key), prefix (tinytext)

Seems like it does work, thank you! I’d update the version given on the Getting Started page, it’d help beginners “fix” issues like this one
