Issue with Discord bot deployment

Hi, so I'm very new to all these stuffs. I just want one bot to run in my discord server, and that requires manual hosting of it. Here's the source code: https://github.com/cheran-senthil/TLE I tried to create project inside railway.app then configured my github and selected the forked repo. But later it seems to use Dockerfile to host it (again I'm not sure) and it's also giving some sort or error. Here's the complete build log screenshot. If possible, help me with it. Might learn a bit of stuff as well. Thank You!
