# Google Workspace CLI Troubleshooting

Common errors, fixes, and platform-specific guidance for the `gws` CLI.

---

## Installation Issues

### gws not found on PATH

**Error:** `command not found: gws`

**Fixes:**
```bash
# Check if installed
npm list -g @anthropic/gws 2>/dev/null || echo "Not installed via npm"
which gws || echo "Not on PATH"

# Install via npm
npm install -g @anthropic/gws

# If npm global bin not on PATH
export PATH="$(npm config get prefix)/bin:$PATH"
# Add to ~/.zshrc or ~/.bashrc for persistence
```

### npm permission errors

**Error:** `EACCES: permission denied`

**Fixes:**
```bash
# Option 1: Fix npm prefix (recommended)
mkdir -p ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH

# Option 2: Use npx without installing
npx @anthropic/gws --version
```

### Cargo build failures

**Error:** `error[E0463]: can't find crate`

**Fixes:**
```bash
# Ensure Rust is up to date
rustup update stable

# Clean build
cargo clean && cargo install gws-cli
```

## Authentication Errors

### Token expired

**Error:** `401 Unauthorized: Token has been expired or revoked`

**Cause:** OAuth tokens expire after 1 hour.

**Fix:**
```bash
gws auth refresh
# If refresh fails:
gws auth setup  # Re-authenticate
```

### Insufficient scopes

**Error:** `403 Forbidden: Request had insufficient authentication scopes`

**Fix:**
```bash
# Check current scopes
gws auth status --json | grep scopes

# Re-auth with additional scopes
gws auth setup --scopes gmail,drive,calendar,sheets,tasks

# Or list required scopes for a service
python3 scripts/auth_setup_guide.py --scopes gmail,drive
```

### Keyring/keychain errors

**Error:** `Failed to access keyring` or `SecKeychainFindGenericPassword failed`

**Fixes:**
```bash
# macOS: Unlock keychain
security unlock-keychain ~/Library/Keychains/login.keychain-db

# Linux: Install keyring backend
sudo apt install gnome-keyring  # or libsecret

# Fallback: Use file-based token storage
export GWS_TOKEN_PATH=~/.config/gws/token.json
gws auth setup
```

### Service account delegation errors

**Error:** `403: Not Authorized to access this resource/api`

**Fix:**
1. Verify domain-wide delegation is enabled on the service account
2. Verify client ID is authorized in Admin Console > Security > API Controls
3. Verify scopes match exactly (no trailing slashes)
4. Verify `GWS_DELEGATED_USER` is a valid admin account

```bash
# Debug
echo $GWS_SERVICE_ACCOUNT_KEY  # Should point to valid JSON key file
echo $GWS_DELEGATED_USER       # Should be admin@yourdomain.com
gws auth status --json          # Check auth details
```

## API Errors

### Rate limit exceeded (429)

**Error:** `429 Too Many Requests: Rate Limit Exceeded`

**Cause:** Google Workspace APIs have per-user, per-service rate limits.

**Fix:**
```bash
# Add delays between bulk operations
for id in $(cat file_ids.txt); do
    gws drive files get $id --json >> results.json
    sleep 0.5  # 500ms delay
done

# Use --limit to reduce result size
gws drive files list --limit 100 --json

# For admin operations, batch in groups of 50
```

**Rate limits by service:**
| Service | Limit |
|---------|-------|
| Gmail | 250 quota units/second/user |
| Drive | 1,000 requests/100 seconds/user |
| Sheets | 60 read requests/minute/user |
| Calendar | 500 requests/100 seconds/user |
| Admin SDK | 2,400 requests/minute |

### Permission denied (403)

**Error:** `403 Forbidden: The caller does not have permission`

**Causes and fixes:**
1. **Wrong scope** — Re-auth with correct scopes
2. **Not the file owner** — Request access from the owner
3. **Domain policy** — Check Admin Console sharing policies
4. **API not enabled** — Enable the API in Google Cloud Console

```bash
# Check which APIs are enabled
gws schema --list

# Enable an API
# Go to: console.cloud.google.com > APIs & Services > Library
```

### Not found (404)

**Error:** `404 Not Found: File not found`

**Causes:**
1. File was deleted or moved to trash
2. File ID is incorrect
3. No permission to see the file

```bash
# Check trash
gws drive files list --query "trashed=true and name='filename'" --json

# Verify file ID
gws drive files get <fileId> --json
```

---

## Output Parsing Issues

### NDJSON vs JSON array

**Problem:** Output format varies between commands and versions.

```bash
# Force JSON array output
gws drive files list --json

# Force NDJSON output
gws drive files list --format ndjson

# Handle both in output_analyzer.py (automatic detection)
gws drive files list --json | python3 scripts/output_analyzer.py --count
```

### Pagination

**Problem:** Only partial results returned.

```bash
# Fetch all pages
gws drive files list --page-all --json

# Or set a high limit
gws drive files list --limit 1000 --json

# Check if more pages exist (look for nextPageToken in output)
gws drive files list --limit 100 --json | grep nextPageToken
```

### Empty response

**Problem:** Command returns empty or `{}`.

```bash
# Check auth
gws auth status

# Try with verbose output
gws drive files list --verbose --json

# Check if the service is accessible
gws drive about get --json
```

---

## Platform-Specific Issues

### macOS

**Keychain access prompts:**
```bash
# Allow gws to access keychain without repeated prompts
# In Keychain Access.app, find "gws" entries and set "Allow all applications"

# Or use file-based storage
export GWS_TOKEN_PATH=~/.config/gws/token.json
```

**Browser not opening for OAuth:**
```bash
# If default browser doesn't open
gws auth setup --no-browser
# Copy the URL manually and paste in browser
```

### Linux

**Headless OAuth (no browser):**
```bash
# Use out-of-band flow
gws auth setup --no-browser
# Prints a URL — open on another machine, paste code back

# Or use service account (no browser needed)
export GWS_SERVICE_ACCOUNT_KEY=/path/to/key.json
export GWS_DELEGATED_USER=admin@domain.com
```

**Missing keyring backend:**
```bash
# Install a keyring backend
sudo apt install gnome-keyring libsecret-1-dev

# Or use file-based storage
export GWS_TOKEN_PATH=~/.config/gws/token.json
```

### Windows

**PATH issues:**
```powershell
# Add npm global bin to PATH
$env:PATH += ";$(npm config get prefix)\bin"

# Or use npx
npx @anthropic/gws --version
```

**PowerShell quoting:**
```powershell
# Use single quotes for JSON arguments
gws gmail users.settings.filters create me `
  --criteria '{"from":"test@example.com"}' `
  --action '{"addLabelIds":["Label_1"]}'
```
