We're currently using **Elastic Observability (serverless)** and encountering an issue when calling the **Create Annotation API**.

Despite the annotation eventually being created, the API call returns a **502 Bad Gateway** response with the following message:

```auto
{ ok: false, message: 'backend closed connection' }

```

Additional details:

- The 502 response is received **after a long wait**.
- The annotation does appear to be created **successfully after some time** , even though the API call fails.

Has anyone else experienced this? Is this expected behaviour in the serverless environment, or could this indicate a backend issue?

Also facing the same issue by creating an annotation from the UI

Any insights or suggestions would be appreciated.
