Facing the same issue as well.

Hi @yangmingbai - is it possible the api is returning an empty string in res_data["data"]["images"]?

@sachin-aakash , are you using the same demo?

[yangmingbai]

@freddyaboulton，Thanks,This is an error raised by requests, requests.Post throw an error "Connection aborted.RemoteDisconnected('Remote end closed connection without response')", Thanks again！

Hi @yangmingbai - is it possible the api is returning an empty string in res_data["data"]["images"]?

@sachin-aakash , are you using the same demo?

No, here is my code and the error -

def pdf_process(file):
    pdf_file_path = file
    dir_location = os.path.dirname(pdf_file_path[0])
    filename = os.path.split(pdf_file_path[0])
    pdf_name = filename[1].split(".pdf")[0]
    command = ["node", "pdfToImageDynamic.js", quote(pdf_file_path[0]), dir_location, pdf_name]
    subprocess.run(command, check=True)
    image_name = os.path.join(dir_location,pdf_name + ".1.png")
    try:
        elements = partition_image(filename=image_name, strategy=strategy,infer_table_structure=True)
        elements_to_json(elements, filename=f"{image_name}.json")
        output_final =  process_json_file(f"{image_name}.json",dir_location,pdf_name)
        print(output_final)
        return output_final

    except subprocess.CalledProcessError as e:
                       print("Error" + e.output)
                       pass

as you can see it is printing out the path to the file that i am returning -

This code was working fine before i updated gradio to the latest version.
