When I generate a PDF or image using:

image_api_response = a2p_client.Chrome.html_to_image(html, file_name=image_filename)
pdf_api_response = a2p_client.Chrome.html_to_pdf(html,file_name=pdf_filename,)

To download the file I try to use image_api_response.download_pdf() or pdf_api_response.download_pdf() I get the following error:

File "/usr/local/lib/python3.8/site-packages/api2pdf/api2pdf.py", line 158, in download_pdf
    if self.result['success']:

The immediate fix:

I also recommend a change in this method's name since it isn't only used to download images. Perhaps download_file.
