The command I run in terminal is as follows:
gvm-script --gmp-username admin --gmp-password admin socket --DESKTOP-9E60Q4 pdf-report.gmp.py 571b5828-12fe-4b78-9c55-2ff0095ed385

The error I received is as follows

Error:
'NoneType' object has no attribute 'encode'

Someone please help me solving this error, it is needed for my project.

    report_element = response.find("report")
    # get the full content of the report element
    content = report_element.find("report_format").tail
 
    # convert content to 8-bit ASCII bytes
    binary_base64_encoded_pdf = content.encode('ascii')
