I built my project on Flask. It has one part that uploads docx extension file and two fields in post request. It is working well. However, when I send docx file that contains images, flask project cannot see the file in the request. I have tried to send docx file with image using JetBrains’ HTTP Client feature, it worked well.
I will provide below all necessary codes and images related to my problem:

If something else is required from my code I can provide.
