The file .env.example doesn't exist when it's trying to copy it.
Also, there's no need to copy a .env.example file. You can directly inject environment variables into the container (or during build time) as needed.

kinda don't understadn

there is no .env.example

Exactly, that's the issue.

not sure where this came from

it's trying to copy something that doesn't exist.

Update your Dockerfile such that it's not trying to copy the .env.example file.

im not using Docker?

im using railpack

i have also docker build which works

My bad.
Is there a Railpack configuration file somewhere?

im trying to get railpack workign

nope :/

all i have is

bun run --filter '@projects/platform' build <- for the bulld
bun run --filter '@projects/platform' start <- for deploy

thats it

Any ideas :/

Just as quick fix i have added .env.example but i still don't understand why defaults railpack require .env.example
