Duplicated OTEL trace in Agent Runtime with BQAA plugin

[guillaumeblaquiere]

#Description#

We are experiencing trace duplication in the Agent Runtime trace section when the bq_plugin is active in the App. When the plugin is commented out (deactivated), the traces appear normal, suggesting an issue with how the plugin generates or interacts with OpenTelemetry traces.

##Configuration##

App ID: 1361960655279620096
Environment Variables:
GOOGLE_GENAI_USE_VERTEXAI=TRUE
BQ_AGENT_GOOGLE_CLOUD_PROJECT=c4-blaquiere-sbx
BQ_AGENT_ANALYTICS_DATASET_ID=agent_data
BQ_AGENT_EVENTS_TABLE_ID=agent_engine_data
GOOGLE_CLOUD_AGENT_ENGINE_ENABLE_TELEMETRY=true
OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=true

##Deployment Command##

adk deploy agent_engine \
                   --project=$PROJECT_ID \
                   --region=$LOCATION_ID \
                   --display_name="Test_ADK_guillaume" \
                   --requirements_file=requirements.txt \
                   --adk_app_object=app \
                   --agent_engine_id="projects/424469508234/locations/europe-west1/reasoningEngines/1361960655279620096" \
                   root_agent

##Relevant Code Snippet##

app = App(
    name="root_agent",
    root_agent=root_agent,
    plugins=[bq_plugin]
)

#Observed Behavior#

When the bq_plugin is included in the App, extra traces are generated in the Agent Runtime trace section compared to when the plugin is deactivated
