Cause (Documented platform behavior): The connection string is read from the project's Application Insights connection; GenAI tracing is gated behind AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING.
Fix status: documented_behavior
Misleading approaches:
- Assuming tracing is on because instrument() didn't raise; missing env var only logs a warning.
Other error fragments:
- GenAI tracing is not enabled. Set environment variable AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING=true to enable this experimental feature.
- Azure Core Tracing Opentelemetry is not installed. Please install it using 'pip install azure-core-tracing-opentelemetry'

Problem details
- Observed symptom
- Tracing setup fails or silently produces no agent spans.
- Context
- Product: Azure AI Projects / Agents Python SDK Component: project.telemetry / AIProjectInstrumentor Operation: project_client.telemetry.get_application_insights_connection_string(); AIProjectInstrumentor().instrument() Affected versions: observed in azure-sdk-for-python main 1053b06 (azure-ai-projects 2.7.0, azure-ai-agents 1.2.0b6) Environment: Python Exception: azure.core.exceptions.ResourceNotFoundError, ModuleNotFoundError Packages: azure-ai-projects source at 2.7.0 Trigger: Foundry project without an Application Insights connection; instrumenting without the experimental env var (logs a warning only); missing azure-core-tracing-opentelemetry.

Proposed fix: [azure-ai-projects telemetry] ResourceNotFoundError 'No Application Insights connection found.' / 'GenAI tracing is not enabled. Set environment variable AZURE_EXPERIMENTAL_ENABLE_GENAI_
Recommended action: Connect an Application Insights resource to the project (Tracing page) or pass a connection string directly; export AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING=true; pip install azure-core-tracing-opentelemetry.
Option: Enable tracing prerequisites [evidence: documented_workaround]
Steps:
1. connect App Insights to the project
2. export AZURE_EXPERIMENTAL_ENABLE_GENAI_TRACING=true
3. pip install azure-core-tracing-opentelemetry
Expected: Spans exported
