Multiple repositories found: ${repoPaths.join(", ")}. Use --

Error message

Multiple repositories found: ${repoPaths.join(", ")}. Use --repository to specify which one to ${operation || "use"}.

What it means

When a workspace has multiple git-sync repositories and the CLI session is non-interactive (no TTY), `selectRepository` cannot prompt for a choice, so it throws listing all repository paths and tells the caller to pass `--repository`.

Solutions

Pass the repository explicitly: add `--repository <repo-path>` to the command
Run in an interactive terminal to get the selection prompt
Remove or consolidate unused repositories so only one remains (then selection is automatic)

Example fix

// before (CI, non-interactive)
wmill git-sync pull
// Multiple repositories found: repo_a, repo_b ...
// after
wmill git-sync pull --repository repo_a

Defensive patterns

Strategy: validation

Validate before calling

const repos = await client.listGitSyncRepositories();
if (repos.length > 1 && !process.stdout.isTTY && !process.env.CI_REPO_FLAG_SET) {
  throw new Error('Non-interactive session with multiple repos: pass --repository <path>');
}

Try / catch

try {
  await runGitSyncCommand();
} catch (e) {
  if (e.message.startsWith('Multiple repositories found:')) {
    const first = e.message.match(/found: ([^.]*)/)?.[1].split(', ')[0];
    console.error(`Re-run with --repository ${first} (or your choice).`);
  } else throw e;
}

Prevention

Always pass --repository explicitly in CI/scripts; don't rely on interactive prompts
Keep one default repository per workspace when automation is involved
If shells hide TTY status (piped output), force explicit flags

When it happens

Trigger: Running any repository-scoped CLI command with 2+ repositories configured while stdin/stdout are not TTYs (CI pipelines, scripts, piped output), without the `--repository` flag.

Common situations: CI/CD jobs (GitHub Actions, GitLab CI) after a second repo was added to the workspace; running the CLI under a wrapper that hides the TTY.
