Unpermitted parameter: :image. (carrierwave )

i am creating a form where you can upload the image file, but whenever i submit the form, it dosent permit the image and in the terminal it shows "Unpermitted parameter: :image. Context: { controller: InstrumentsController, action: update, request: #ActionDispatch::Request:0x00007f1955b24b50, params: {"_me................."

also if i check using the rails console if the image is being uploaded or not by typing the Instrument.all (Instrument is a table in database), it shows that it is nil,

i have permitted the :image in params

instruments_controller.rb

class InstrumentsController < ApplicationController
  before_action :set_instrument, only: %i[ show edit update destroy ]
  before_action :authenticate_user!, except: [:index, :show]

  # GET /instruments or /instruments.json
  def index
    @instruments = Instrument.all.order("created_at desc")
  end

  # GET /instruments/1 or /instruments/1.json
  def show
  end

  # GET /instruments/new
  def new
    @instrument = current_user.instruments.build
  end

  # GET /instruments/1/edit
  def edit
  end

  # POST /instruments or /instruments.json
  def create
    @instrument = current_user.instruments.build(instrument_params)

    respond_to do |format|
      if @instrument.save
        format.html { redirect_to instrument_url(@instrument), notice: "Instrument was successfully created." }
        format.json { render :show, status: :created, location: @instrument }
      else
        format.html { render :new, status: :unprocessable_entity }
        format.json { render json: @instrument.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /instruments/1 or /instruments/1.json
  def update
    respond_to do |format|
      if @instrument.update(instrument_params)
        format.html { redirect_to instrument_url(@instrument), notice: "Instrument was successfully updated." }
        format.json { render :show, status: :ok, location: @instrument }
      else
        format.html { render :edit, status: :unprocessable_entity }
        format.json { render json: @instrument.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /instruments/1 or /instruments/1.json
  def destroy
    @instrument.destroy

    respond_to do |format|
      format.html { redirect_to instruments_url, notice: "Instrument was successfully destroyed." }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_instrument
      @instrument = Instrument.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def instrument_params
      params.require(:instrument).permit(:brand, :model, :description, :condition, :finish, :tiitle, :price, :image)
    end
end

and inside the model (ignore 'tiitle' as i have already done a typo and continue to use it instead of 'title')

instrument.rb

class Instrument < ApplicationRecord
    
    mount_uploader :image, ImageUploader

    belongs_to :user, optional: true
    

    validates :tiitle, :brand, :price, :model, presence: true
    validates :description, length: { maximum: 1000, too_long: "%{count} is the maximum allowed characters" }
    validates :tiitle, length: { maximum: 140, too_long: "%{count} is the maximum allowed characters" } 
    validates :price, numericality: { only_integer: true }, length: { maximum: 7 } 

    BRAND = %w{ Fender Gibson Epiphone ESP Martin Dean Taylor Jackson PRS Ibanez Charvel Washburn }
    FINISH = %w{ Black White Navy Blue Red Clear Satin Yellow Seafoam }
    CONDITION = %w{ New Excellent Mint Used Fair Poor }

i am a newbie, according to the knowledge what i have understood is that we have to use html: {multipart: true} in the form initializing so that it accepts the uploader as file and permit the ':image' in controller's file and it should work but when i click the "Create" button, it dosen't upload the image and shows unpermitted params in terminal while i submit it and creates a new instrument with all fields except the uploader. Any fixes? :')
