So my deployement failed even tho I haven't made any configuration changes. I am using Django in my app and nixpacks builder as default builder here on Railway.

Here are the logs of the error, I also seen that people had issues with this two months ago but that fix which they came up with doesn't work for me. Hope people can help out:

error:

Did you mean doc?

Like I said I made no changes so nothing is breaking in my code, no missconfiguration or anything like that.
