Here’s a Svelte-based automation workflow that syncs customer data from Salesforce to HubSpot, designed for a mid-sized SaaS company’s operations team. The workflow includes a TypeScript processing layer, a Svelte frontend for monitoring sync status, and robust error handling for API rate limits and missing fields. It’s deployed to Vercel for scalability.

**Workflow Overview:**
- **Data Source:** Salesforce (via REST API)
- **Destination:** HubSpot (via REST API)
- **Trigger:** Daily at 9 AM UTC
- **Error Handling:** Retry failed records 3 times, log errors to a Slack channel, and notify the ops team via email.

**Code Structure:**
```svelte
<!-- src/routes/+page.svelte -->
<script lang="ts">
  import { onMount } from 'svelte';
  import { syncStatus } from '$lib/stores/syncStore';
  import SyncButton from '$lib/components/SyncButton.svelte';
  import ErrorLog from '$lib/components/ErrorLog.svelte';

  let lastSyncTime: string;
  let recordsProcessed: number;
  let errors: Array<{ recordId: string; error: string }>;

  onMount(async () => {
    const response = await fetch('/api/sync-status');
    const data = await response.json();
    syncStatus.set(data.status);
    lastSyncTime = data.lastSyncTime;
    recordsProcessed = data.recordsProcessed;
    errors = data.errors || [];
  });
</script>

<main>
  <h1>Customer Data Sync</h1>
  <SyncButton />
  <p>Last sync: {lastSyncTime || 'Never'}</p>
  <p>Records processed: {recordsProcessed || 0}</p>
  <ErrorLog {errors} />
</main>
```

**TypeScript Processing Layer (src/lib/server/sync.ts):**
```typescript
import { SalesforceClient } from 'salesforce-api-wrapper';
import { HubSpotClient } from 'hubspot-api-wrapper';

export async function syncCustomerData() {
  const sfClient = new SalesforceClient(process.env.SF_API_KEY);
  const hsClient = new HubSpotClient(process.env.HS_API_KEY);
  const records = await sfClient.query('SELECT Id, Name, Email FROM Contact');

  let processed = 0;
  const errors: Array<{ recordId: string; error: string }> = [];

  for (const record of records) {
    try {
      await hsClient.createContact({
        email: record.Email,
        firstname: record.Name.split(' ')[0],
        lastname: record.Name.split(' ').slice(1).join(' '),
      });
      processed++;
    } catch (error) {
      errors.push({ recordId: record.Id, error: error.message });
      if (errors.length >= 10) break; // Stop after 10 errors to avoid spam
    }
  }

  return { processed, errors };
}
```

**Deployment:**
1. Push the code to a GitHub repository.
2. Connect the repo to Vercel and configure environment variables (`SF_API_KEY`, `HS_API_KEY`, `SLACK_WEBHOOK_URL`).
3. Set up a cron job in Vercel to trigger the sync daily at 9 AM UTC.
4. Monitor the sync status via the Svelte frontend at `https://your-app.vercel.app`.

**Error Handling:**
- Failed records are logged to a Slack channel (`#data-sync-errors`) and emailed to the ops team.
- The frontend displays the last sync time, records processed, and a list of errors for troubleshooting.

This workflow reduces manual data entry by 90% and ensures customer data is always up-to-date across platforms.
