Is there a way of using FPDF to generate a PDF file from forms in Django?

Question

I am trying to generate a PDF file and give it a custom name using Django 4.0.2 I have 2 inputs, one for the name and one for the photos, I want to be able to generate the PDF without saving it in my database but return it back to the user. I am using no models for this, plain html and python. I have the inputs:

<input
                    type="text"
                    id="inputPassword6"
                    class="form-control"
                    aria-describedby="passwordHelpInline"
                    name="name"
                />
<input
                    class="form-control"
                    type="file"
                    id="formFileMultiple"
                    multiple
                    accept=".png, .jpeg, .jpg"
                    name="photos"
                />
        <div class="d-grid gap-2 mt-3">
            <button class="btn btn-success" type="submit">Save PDF</button>
        </div>

And I am trying to merge and return the PDF file like this:

    if request.method == "POST" or "FILES":
        name = request.POST["name"]
        photos = request.FILES["photos"]

        # Convert photos to PDF
        pdf = FPDF()
        # imagelist is the list with all image filenames
        for image in photos:
            pdf.add_page()
            pdf.image(image, 0,0,210,297)
        pdf.output(f"{name} AIA 114.pdf", "F")

Current error:

Exception Type: TypeError
Exception Value:    
argument should be integer or bytes-like object, not 'str'

It looks like FPDF can not look into the image I provided. I tried to decode the image, but I hit another error:

'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

Can someone help me solve this problem or propose another way of doing it?
