Why does this limit matter?
Deleting an attachment later does not reverse the quota that was counted when it was stored.
This value is scoped to Stored event attachments; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Monitor attachment quota and export necessary diagnostics before the 30-day window ends.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- Event retention and attachment storage access can have separate organization settings.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
