Unhandled error event when using Figma connect

[thomtreebus]

I'm trying to use the interactive setup to connect my design system to code connect. When asked for the URL of the Figma file with my design system library (step 3 in the guide), I get this error:

node:events:497
      throw er; // Unhandled 'error' event
      ^

Error: write EPIPE
    at WriteWrap.onWriteComplete [as oncomplete] (node:internal/stream_base_commons:94:16)
Emitted 'error' event on Socket instance at:

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  errno: -32,
  code: 'EPIPE',
  syscall: 'write'
}

Node.js v21.7.1

I tried running swift run -c release --verbose figma-swift, which produced the following error:

error: binary operator '??' cannot be applied to operands of type '(output: String, changes: [Formatter.Change])?' and 'String'

• Code Connect CLI version: 1.1.2
• Operating system: OSX

figma.config for my SwiftUI project:

{
  "codeConnect": {
    "swiftPackagePath": "Package.swift",
    "include": ["Sources/**/**/*"],
    "exclude": ["markdown/**", "danger/**", "scripts/**", "SnapshotTests/**"]
  }
}

My Package.swift setup:

import PackageDescription

let package = Package(
    name: "ProjectName",
    defaultLocalization: "en",
    platforms: [
        .macOS(.v14),
        .iOS(.v16)
    ],
    products: [
        .library(name: "ProjectName", targets: ["ProjectTarget"])
    ],
    dependencies: [
        ...
        .package(url: "https://github.com/figma/code-connect", from: "1.0.0"),
    ],
    targets: [
        .target(name: "ProjectTarget",
            dependencies: [
                ...
                .product(name: "Figma", package: "code-connect")
            ],
            path: "Path/To/Project"
        )
    ]

Hi @thomtreebus, thanks for the report! We've identified the issue and working on a fix.

In the meantime if you can force the version for SwiftFormat of 0.53.5 in your project that should fix the issue in the meantime. Sorry for the inconvenience.
