How do I fix this aspose-pdf-cloud-python script to successfully download a processed PDF file from aspose storage?
Environment:

• Windows 11 23H2;
• Python 3.11.4;

import os
from asposepdfcloud import PdfApi, models
from asposepdfcloud.api_client import ApiClient

# Replace with your Aspose Cloud App key and App SID
app_key = 'app_key personal'
app_sid = 'app_sid personal'

# Initialize the PdfApi client
pdf_api_client = ApiClient(app_key=app_key, app_sid=app_sid)
pdf_api = PdfApi(pdf_api_client)

def process_pdf_files_in_folder(input_folder, output_folder):
    # Ensure the output folder exists
    os.makedirs(output_folder, exist_ok=True)

    # Iterate over all PDF files in the input folder
    for filename in os.listdir(input_folder):
        if filename.endswith(".pdf"):
            input_file_path = os.path.join(input_folder, filename)
            remote_name = filename
            copied_file = f'processed_{filename}'
            
            # Upload PDF file to cloud storage
            pdf_api.upload_file(remote_name, input_file_path)

            # Copy the file
            pdf_api.copy_file(remote_name, copied_file)

            # Replace text
            text_replace = models.TextReplace(old_value='Watermark instead', new_value='', regex=True)
            text_replace_list = models.TextReplaceListRequest(text_replaces=[text_replace])
            pdf_api.post_document_text_replace(copied_file, text_replace_list)
            
            # Download the processed file to the local system
            output_file_path = os.path.join(output_folder, copied_file)
            
            # Retrieve the file content from the cloud
            response = pdf_api.download_file(copied_file)
            
            # Open a file stream to write the downloaded content
            with open(output_file_path, 'wb') as file:
                # Write the content to the file
                file.write(response)

            print(f'Processed and saved: {output_file_path}')

# Use specific folder paths
process_pdf_files_in_folder(r'D:input', r'D:output')

The error when running the code is as follows:

D:>python rm.py
host: https://api.aspose.cloud/v3.0
tokenUrl: https://api.aspose.cloud/connect/token
Traceback (most recent call last):
  File "D:rm.py", line 49, in <module>
    process_pdf_files_in_folder(r'D:input', r'D:output')
  File "D:rm.py", line 44, in process_pdf_files_in_folder
    file.write(response)
TypeError: a bytes-like object is required, not 'str'

Multiple modify to the code still don’t work, need a runnable code.
