i dont know why this error

I don't know if the problem is in the database or in relation to the media, but when I upload the project this error appears, I've already researched several things and I can't find a solution

Answer 1

Happens to encounter same error. I found out from searching the web that services on railway generally use ubuntu and packages that are available only for windows may cause the docker build error. I checked my requirements.txt and removed all unneeded packages that are listed automatically when I used pip freeze command and that solves my problem.
