Error message

Extension temp directory not found. Make sure packaging completed successfully.

What it means

Thrown by copyExtensionToReleaseFolder() when apps/vscode/extension/temp/ does not exist. The temp dir is supposed to hold the packaged .vsix produced by the preceding `yarn package` step. If it is missing, packaging failed, did not run, or wrote to a different location.

Solutions

1. Run `yarn package` manually in apps/vscode/extension and check its output for errors
2. Verify the package script writes the .vsix into ./temp
3. Ensure the prerequisite `yarn lazy run build --filter=packages/*` completed successfully before packaging
4. Check that cwd is the repo root so the relative temp path resolves

// check that packaging actually produced a vsix before copying
const tempDir = path.join(EXTENSION_DIR, 'temp')
if (!existsSync(tempDir) || readdirSync(tempDir).some((f) => f.endsWith('.vsix')) === false) {
  throw new Error('Packaging did not produce a .vsix in temp — run yarn package and inspect its output')
}

When it happens

Trigger: existsSync(path.join(EXTENSION_DIR, 'temp')) returns false, after `yarn package` (production) or `yarn package --pre-release` (staging) was supposed to run.

Common situations: `yarn package` failed but the error was swallowed or this function was reached anyway; the package script changed its output directory; clean working tree where temp is gitignored and never created; the build step (`yarn lazy run build --filter=packages/*`) that package depends on failed earlier.
