python manage.py collectstatic not working: TypeError: sequence item 0: expected str instance, NoneType found – Amazon web services

I have been following this video on Youtube: https://www.youtube.com/watch?v=inQyZ7zFMHM1

My project so far is working fine with static files and all the files load and work properly. So, now I have to deploy the website on Heroku and for that, I uploaded the database on Amazon AWS using this video.

After bucket creation, I did the configurations as mentioned in the video (copied the static files into the Bucket AWS) but it didn’t work for me. It always showed me an error, that failed to load the resources

On searching, I found the command python manage.py collectstatic to upload files into Bucket so I tried it out but this is the error I keep on getting

TypeError: sequence item 0: expected str instance, NoneType found

I have searched a lot on this but unable to figure out what is the issue. This is also the same error which I got when I myself uploaded static files into Bucket and tried to upload a Profile Image
