[BUG] Agent Observability Dashboard: Missing index-pattern-fields for GenAI attributes

[brijos]

Description:

Multiple panels in the "Agent Observability" dashboard are failing to load data because the required index pattern fields cannot be located. The dashboard appears to be looking for OpenTelemetry GenAI semantic convention attributes that are either not indexed or mapped incorrectly in the default logs-otel-v1* pattern.

Panels Affected:

• Request Model (attributes.gen_ai.request.model)
• Tool Name (attributes.gen_ai.tool.name)
• Input Tokens (attributes.gen_ai.usage.input_tokens)
• Operation Name (attributes.gen_ai.operation.name)

Steps to reproduce:

Open Dashboards -> Observability -> Dashboards.
Select the Agent Observability dashboard.
Observe the error: Could not locate that index-pattern-field (id: ...) on at least 4 visualization panels.

Expected behavior:

The dashboard should gracefully handle missing fields or provide a clear setup guide to ensure OTel GenAI attributes are correctly mapped as keywords or long values during ingestion.

@brijos tried reproducing this and it appears there's a ~1-2 minute window on very first boot when no logs/trace data is available because it's still being ingested/indexing. Is this what you're referring to or is there always no data? Screenshot below on latest branch/commit for reference:
