# Tracking and personalization suspended

Resolve tracking and personalization suspended errors.

The workspace has [suspended services](/explanation/workspace/service-suspension).

This error is only returned to clients running SDK versions older than `v0.19.1`. Newer SDK versions receive a `202 Accepted` empty response instead, which they handle silently by falling back to [default content](/explanation/content/fallback-content).

> **Upgrade the SDK**
>
> Upgrade the Croct SDK to `v0.19.1` or later so that suspended workspaces return an empty `202 Accepted` response your client can handle gracefully.

## Response
