## Troubleshooting

### Common Migration Issues

#### Issue: Import fails with "Invalid format"

**Solution**:
- Ensure NDJSON files have one valid JSON object per line
- Check for UTF-8 encoding
- Validate JSON syntax with `jq`:
  ```bash
  cat documents.ndjson | jq empty
  ```

#### Issue: GSA XML import creates no configurations

**Solution**:

    @Test
    public void test_isAcceptCookieLocale() {
        // Always returns false as per implementation
        assertFalse(provider.isAcceptCookieLocale());
    }

    // Test findBusinessLocale with valid locale parameter
    @Test
    public void test_findBusinessLocale_withValidLocale() {
        // Setup mock config
        FessConfig mockConfig = new FessConfig.SimpleImpl() {
            @Override
