Hey there! We've found the following might help you get unblocked faster:

• 🧵 Revert Nixpacks Version

• 🧵 Subtle(?) Railpack build difference

• 🧵 Railway ignoring Node 20 configuration (Nixpacks using Node 18) → causing repeated 502 failures

If you find the answer from one of these, please let us know by solving the thread!

I started experiencing the same thing yesterday, and stumbled upon this message (about Nixpacks being depricated) in my settings

Error thrown during build:

downloading build driver nixpacks-1.29.1 from https://github.com/railwayapp/nixpacks/releases/download/1.29.1/nixpacks-1.29.1-x86_64-unknown-linux-musl.tar.gz

failed to download build driver

Also tried RAILPACK but to no avail:

"$schema": "https://railway.app/railway.schema.json",

"build": {

"builder": "RAILPACK"

},

"NIXPACKS_VERSION":"v1.29.1"

The above has soled the issue for now.
Till now the below was working fine
"NIXPACKS_VERSION":"1.29.1"
