how to skip experimental_allow_proto3_optional

[azharimad]

This is how to resolved experimental_allow_proto3

Install
sudo apt update && sudo apt install -y protobuf-compiler

after modify build.rs run cargo with cargo run -r -- start --env beta

modify build.rs to this

use prost_build::Config;
use std::{env, error::Error, fs, path::Path, process::Command};

fn main() -> Result<(), Box<dyn Error>> {
    // Tell cargo to recompile if any of these files change
    println!("cargo:rerun-if-changed=proto/orchestrator.proto");
    println!("cargo:rerun-if-changed=build.rs");

    let proto_path = Path::new("proto/orchestrator.proto");

    // Print current directory
    println!("Current dir: {:?}", env::current_dir()?);

    // Check if proto file exists
    if !proto_path.exists() {
        println!("Error: Proto file not found at {:?}", proto_path);
        return Err("Proto file not found".into());
    }
    println!("Found proto file at {:?}", proto_path.canonicalize()?);

    let out_dir = "src/proto";

    // Check if protoc is installed and accessible
    let output = Command::new("which")
        .arg("protoc")
        .output()
        .expect("Failed to execute command");

    if output.status.success() {
        println!("protoc is installed and accessible.");
    } else {
        println!("Error: protoc is not installed or not in PATH.");
        return Err("protoc not found".into());
    }

    // Ensure the output directory exists
    if !Path::new(out_dir).exists() {
        fs::create_dir_all(out_dir)?;
        println!("Created output directory: {}", out_dir);
    } else {
        println!("Output directory exists: {}", out_dir);
    }

    // Configure prost_build and compile .proto files
    let mut config = Config::new();
    config.out_dir(out_dir);

    match config
        .protoc_arg("--experimental_allow_proto3_optional") // Tambahkan flag ini
        .compile_protos(&["proto/orchestrator.proto"], &["proto"])
    {
        Ok(_) => println!("Successfully compiled protobuf files."),
        Err(e) => {
            println!("Error compiling protobuf files: {}", e);
            return Err(Box::new(e));
        }
    }

    // Print the generated file path
    let generated_file_path = format!("{}/orchestrator.rs", out_dir);
    if Path::new(&generated_file_path).exists() {
        println!("Generated file exists: {}", generated_file_path);
    } else {
        println!("Error: Generated file does not exist at {}", generated_file_path);
        return Err("Generated file not found".into());
    }

    Ok(())
}

di .nexus/network-api/clients/cli/src/proto
rename nexus.orchestrator.rs jadi orchestrator.rs

isi file orchestrator apa y bang? w cb buka no such file or directory soalnya
