Hello,
I’m encountering an issue while trying to rebuild my project in Railway. About three months ago, I uploaded the project without any problems. Recently, I only added a single line of code, but when I tried to upload it again, I got the following error:

I haven’t made any significant changes, other than this one line. I’ve tried searching for solutions but haven’t found anything that fixes the issue. Can anyone advise on what steps I need to take to resolve this error?
Thank you for your help!

Try this steps. Its helps me to slve my problem. I think, configuration changed. I also haven’t done deployments for about a month.
In the root directory of your project, create a file named
nixpacks.toml. This file allows you to specify custom dependencies for Nixpacks.Add the Correct Dependencies
Add the following configuration to yournixpacks.tomlfile:[phases.setup] nixPkgs = ["gcc", "postgresql_16", "python39"]Note! - These parameters apply to my project. You may have others
gcc: Ensures the availability of a C compiler for building dependencies.postgresql_16: Installs the correct version of PostgreSQL. (My version is 16, so the result ispostgresql_16)python39: Installs Python <version> for your project. (My version is 3.9, so the result ispython39)
