No but now compilation failed inside the Rust build with include_str!("../db/schema.sql");:

I'm not a Rust dev so I don't know how to fix it :/

   Compiling backend v0.1.0 (/app)
error: couldn't read src/../db/schema.sql: No such file or directory (os error 2)

   = note: this error originates in the macro `include_str` (in Nightly builds, run with -Z macro-backtrace for more info)

error: could not compile `backend` (bin "backend") due to previous error
The command '/bin/sh -c cargo build --release' returned a non-zero code: 101

@mielune can you confirm if you have the db directory and inside it there should be schema.sql file? Attaching the image below for reference.
