Rails Params теряется в params, но присутствует в request.body

Question

У меня есть рабочий проект с формой, но в некоторых случаях во время отправки формы параметры тела запроса не передаются на параметры в контроллере.

Это то, что я вижу, когда кладуbinding.pry внутри контроллера приложения в виде before_action

[1] pry(#<App::Agent::V2::VerificationsController>)> request.url
=> "http://localhost:4567/app/agent/v2/verifications/sg_bug_bash/submit"
[2] pry(#<App::Agent::V2::VerificationsController>)> request.body.read
=> "utf8=%E2%9C%93&authenticity_token=2myJbSTptXGEGn8a14T3zj7cgMSc%2F8zsLI27%2BirR6ZplQotMkTDfGWgKes3k9OSIfnL5wKyFvazn7tvNS9zuHQ%3D%3D&obs_application%5Boperation_name%5D=sg_bug_bash&obs_application%5Bapplication_id%5D=1&commit=Submit%2FDone&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_bank_statement%5D%5Bid%5D=e4c987fb-a875-420e-81db-45a8482d36eb&resubmit_status%5BRotate%5D=0&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_bank_statement%5D%5Brejection_reasons%5D%5B%5D=&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_bank_statement%5D%5Brejection_reasons%5D%5Baccount_number%5D=+not+valid+&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_bank_statement%5D%5Brejection_reasons%5D%5Bbank_code%5D=&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_lta_vehicle_log_card%5D%5Bid%5D=4d6fd458-2a46-4f8b-bf9e-0f7b26ea16f2&resubmit_status%5BRotate%5D=0&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_lta_vehicle_log_card%5D%5Brejection_reasons%5D%5B%5D=&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_lta_vehicle_log_card%5D%5Brejection_reasons%5D%5Bvehicle_plate_number%5D=&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_lta_vehicle_log_card%5D%5Brejection_reasons%5D%5BvehicleBrand%5D=+not+valid+&obs_application%5Bpanels%5D%5Bdocuments%5D%5Bsg_lta_vehicle_log_card%5D%5Brejection_reasons%5D%5BvehicleType%5D="
[3] pry(#<App::Agent::V2::VerificationsController>)> params
=> {"controller"=>"app/agent/v2/verifications", "action"=>"submit", "id"=>"sg_bug_bash"}

Это динамически генерируемая форма, поэтому HTML выглядит следующим образом:

<form id="verification-form" class="edit_obs_application" action="/app/agent/v2/verifications/sg_bug_bash/submit" accept-charset="UTF-8" method="post"><input name="utf8" type="hidden" value="✓"><input type="hidden" name="authenticity_token" value="j1rCDid+EAiODQijn+TNTml/MTwikobF2Tg63ssZ+EtAAH/ebLimZd8C5D1oXhLYHr9EohRvmnSfnmE7ikrSdw==">

                <%= form_for @application, url: retry_application_completion_app_agent_v2_verification_path, method: :post, html: { id: 'verification-form', class: 'col-md-6 text-center' } do |f| %>

<% sections = panel.sections %>
<div class="submit-btn-verification">
  <%= form.submit sections.first.properties['label'], class: 'submit_btn btn btn-valid disabled', disabled: 'disabled', style: 'cursor: not-allowed' %>
