Error on serializing active model object with attr_encryped attribute

[abuzzany]

Hi everyone,

I have an active called TaxableEntity that has the next attr_encryped attribute:

  attr_encrypted(
    :sat_password,
    key: Rails.configuration.creds.fetch(:SECRET_KEY_BASE), attribute: "encrypted_sat_password",
    algorithm: "aes-256-cbc", mode: :single_iv_and_salt, insecure_mode: true
  )

Currently I am using the attr_encrypted from 3.0.3 gem and It works correctly. The problem comes when I bump the gem to 3.10 version. When I use the method as_json on the active model object I get the next error:

irb(main):007:0> t2 = TaxableEntity.select(:id).find(1)
  TaxableEntity Load (0.4ms)  SELECT  "taxable_entities"."id" FROM "taxable_entities" WHERE "taxable_entities"."id" = $1 LIMIT $2  [["id", 1], ["LIMIT", 1]]
=> #<TaxableEntity id: 1, sat_password: nil>
irb(main):008:0> t2.as_json
Traceback (most recent call last):
        1: from (irb):8
ActiveModel::MissingAttributeError (missing attribute: encrypted_sat_password)

but It only happens when use before a select method, without select it works correctly

#<TaxableEntity id: 1, rfc: "TEST010203001", created_at: "2020-06-15 19:56:43", updated_at: "2020-06-15 19:56:43", legal_name: "Resuelve PF", account_holder_id: 3, encrypted_sat_password: nil, tax_classification: "business_activity", employer_registration: "A2410589123", customer_token: nil, user_id: nil, sent_statement: false, service_comments: nil, accountant_comments: nil, zendesk_id: nil, curp: nil, accounting_settings: nil, valid_credentials: true, complexity: nil, paybook_user: nil, legal_type: "individual", status: "demo", active: true, old_services: nil, postal_code: "05200", generation: nil, last_downloaded_invoice_issue_date: nil, last_crawler: nil, sales_comments: nil, fiscal_status: nil, uses_otp: false, sales_user_id: nil, customer_service_user_id: nil, accounting_status: nil, payment_reference: nil, closing_date: nil, conekta: false, expired_payments: 0, migrated_entity: false, sat_password: nil>

Can you help me?
