UnretrievedModelException: the DataType data could not be retrieved for id nothing

An error occurs when I try to save a record. It works fine using SearchLightSQLite.jl

groups.seed()
[ Info: 2020-11-16 19:48:00 INSERT INTO groups ( "type", "name", "active", "deleted" ) VALUES ( E'B', E'Group one', true, false ) RETURNING id

**Groups.jl**

module Groups

import SearchLight: AbstractModel, DbId, save!
import Base: @kwdef

export Group

@kwdef mutable struct Group <: AbstractModel
id::DbId = DbId()
type::String = ""
name::String = ""
active::Bool = true
deleted::Bool = false
end

function seed()
Data = [
("B", "Group one", true, false),
("B", "Group two", true, false)

for b in Data

end
end

end

**2020111423440271_create_table_groups.jl**

module CreateTableGroups

import SearchLight.Migrations: create_table, column, primary_key, add_index, drop_table

function up()
create_table(:groups) do
[
primary_key()
column(:type, :string)
column(:name, :string)
column(:active, :boolean)
column(:deleted, :boolean)
]
end

add_index(:groups, :name)
end

function down()
drop_table(:groups)
end

end

Reproduce the failure with groups.seed() in app/resources/groups/groups.jl, using the migration in 2020111423440271_create_table_groups.jl. Start at save!! in SearchLight.jl line 171 and compare the PostgreSQL path with the reported working SearchLightSQLite.jl path. Done means saving the Group records completes without UnretrievedModelException.
