#Rails ActiveRecord::RecordNotFound in ActiveStorage::BlobsController#show - ruby-on-rails

Question

Getting error of
Couldn't find ActiveStorage::Blob with 'id'=41
I am trying to read blog attachments and see the images and download them. It works sometimes and doesn't works when server is restarted.
My show.html.haml view template is
%h1.page-heading
%a{href: admin_tenant_site_unit_floor_plans_path}
%i.material-icons.left arrow_back
Listing Images
%small= "of Floor Plan #{#floor_plan.id}"
.row
.col.s8
%table.report
%thead
%tr
%th= "Blob_id"
%th= "Name"
%th= "Record type"
%th
%i.material-icons visibility
%th
%i.material-icons download
%tbody
- if #floor_plan.floor_image.attached?
- #floor_plan.floor_image.each do |image|
%tr
%td= image.blob_id
%td= image.name
%td= image.record_type
-# %td= link_to "Download " + image.record_type + " " + image.blob_id.to_s, rails_blob_path(image, disposition: "attachment"), target: '_blank'
%td= link_to "View " + image.record_type + " " + image.blob_id.to_s, url_for(image), target: '_blank'
%td= link_to "Download " + image.record_type + " " + image.blob_id.to_s, rails_blob_path(image, disposition: "attachment"), target: '_blank'
Controller action :
def show
# binding.b
#floor_plan = FloorPlan.find(params[:id])
end
Also index.html.haml :
= render(partial: 'admin/units/sublinks')
%h5.section-heading.mt20
Listing Floor plans
.row
.col.s8
%table.report
%thead
%tr
%th= "Name"
%th= sortable "created_at", "Submission Date"

%td= plan.created_at.strftime("%b %d, %Y %r")

%li

FloorPlan.rd model file :
class FloorPlan < ApplicationRecord
belongs_to :unit
has_many_attached :floor_image, dependent: :destroy
validates :name, presence:true
validates :floor_image, presence:true
end
And here is the snippet from schema.rb
create_table "floor_plans", force: :cascade do |t|
t.string "name", null: false
t.bigint "unit_id", null: false
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
t.index ["unit_id"], name: "index_floor_plans_on_unit_id"
end
The error doesn't come up when the exactly same system I used in other component of the app. But the error is persistent upon clicking the "View" and "Download" links in show and index templates.
Please guide me to resolve this error and to understand the root cause.
Also I wanna print the name of the blob items instead of printing names from the active_storage_attachments table.
