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:
{ 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.
