the above error keeps happening when i use this command:
dl_coursera --cookies coursera\cookies.txt --outdir google-cybersecurity google-cybersecurity

however it worked fine with the meta-full-stack-web-development course

any help? i tried updating my cookies and am enrolled in the course as well, but no luck

[rudraaaaa-05]

it wasn't a course nor a specialization but a professional certificate
managed to download the first module only it by running
coursera_dl --cookies coursera\cookies.txt --outdir "courses/foundations-cybersecurity" foundations-cybersecurity

but the rest are still giving the fileExtenstion error

I may have time to fix it this week.
