The session appeared to be created locally, but spans/events were not being transmitted successfully. + +## Root Cause Analysis + +The issue was caused by an **authentication race condition** in the session initialization flow: + +1. **Asynchronous Authentication**: When `agentops.init()` is called, authentication happens asynchronously in a background thread to avoid blocking the main application. + +2. **Immediate Session Creation**: The session/trace is created immediately with a temporary project ID, and the session URL is logged to the console right away. + +3. **Export Failures**: If spans are exported before authentication completes, they fail because: + - No JWT token is available yet for authorization + - The project ID is still set to "temporary" + - The exporter would fail silently or with minimal logging + +4. **Silent Failures**: The default log level was initially set to `CRITICAL`, causing most error messages to be suppressed, making the issue difficult to diagnose. + +## Timeline of Events + +``` +1. User calls agentops.init(api_key="...") +2. Session URL is logged immediately (e.g., "Session Replay: https://app.agentops.ai/sessions?trace_id=...") +3. Authentication starts in background thread +4. User's code starts generating spans/events +5. Spans try to export but fail (no JWT yet) +6. Authentication completes 1-3 seconds later +7. New spans work, but initial spans are lost +``` + +## The Fix + +### 1. Added Authentication Synchronization + +Added an event-based mechanism to track authentication completion: + +```python +# In Client class +_auth_completed = threading.Event() # Signals when auth is done + +def wait_for_auth(self, timeout: float = 5.0) -> bool: + """Wait for authentication to complete.""" + return self._auth_completed.wait(timeout) +``` + +### 2. New Configuration Options + +Added two new configuration parameters: + +- `wait_for_auth` (default: `True`): Whether to wait for authentication before allowing span exports +- `auth_timeout` (default: `5.0`): Maximum seconds to wait for authentication + +These can be configured via: +- Parameters to `agentops.init()` +- Environment variables: `AGENTOPS_WAIT_FOR_AUTH`, `AGENTOPS_AUTH_TIMEOUT` + +### 3. Improved Exporter Logic + +The `AuthenticatedOTLPExporter` now: +- Checks if JWT is available before attempting export +- Returns `FAILURE` (for retry) instead of attempting unauthorized requests +- Provides better logging for debugging + +### 4. Better Error Visibility + +- Improved logging throughout the authentication flow +- More descriptive error messages when exports fail +- Debug logs show authentication progress + +## Usage Examples + +### Default Behavior (Recommended) + +```python +import agentops + +# Will wait up to 5 seconds for auth to complete +agentops.init(api_key="your-api-key") +# Spans created here will be exported successfully +``` + +### Custom Timeout + +```python +# Wait up to 10 seconds for auth +agentops.init( + api_key="your-api-key", + auth_timeout=10.0 +) +``` + +### Disable Waiting (Previous Behavior) + +```python +# Don't wait for auth (may lose initial spans) +agentops.init( + api_key="your-api-key", + wait_for_auth=False +) +``` + +### Environment Variables + +```bash +export AGENTOPS_WAIT_FOR_AUTH=true +export AGENTOPS_AUTH_TIMEOUT=10.0 +python your_script.py +``` + +## Backward Compatibility + +The fix is **backward compatible**: +- By default, `wait_for_auth=True` ensures spans are not lost +- Users can opt-out by setting `wait_for_auth=False` to restore previous behavior +- The wait is capped by timeout to prevent indefinite blocking +- If authentication fails, the system continues without blocking + +## Testing the Fix + +Run the test script to verify the fix: + +```bash +python test_auth_fix.py +``` + +This will test: +1. With wait_for_auth enabled (default) +2. With wait_for_auth disabled +3. Without an API key + +## Troubleshooting + +If you're still experiencing issues: + +1. **Enable Debug Logging**: + ```python + agentops.init(api_key="...", log_level="DEBUG") + ``` + +2. **Check Network Connectivity**: + - Verify you can reach `https://api.agentops.ai` + - Check for proxy/firewall issues + +3. **Verify API Key**: + - Ensure your API key is valid + - Check for typos or extra spaces + +4. **Increase Timeout**: + ```python + agentops.init(api_key="...", auth_timeout=10.0) + ``` + +## Impact + +This fix resolves the issue where: +- Users see a session URL but no data in the dashboard +- Initial spans/events are lost during session startup +- Authentication failures are silent and hard to debug + +The solution ensures reliable data transmission while maintaining non-blocking initialization for better user experience. \ No newline at end of file diff --git a/agentops/__init__.py b/agentops/__init__.py index 816e77443..d3f1132bc 100755 --- a/agentops/__init__.py +++ b/agentops/__init__.py @@ -92,6 +92,8 @@ def init( fail_safe: Optional[bool] = None, log_session_replay_url: Optional[bool] = None, exporter_endpoint: Optional[str] = None, + wait_for_auth: Optional[bool] = None, + auth_timeout: Optional[float] = None, **kwargs, ): """ @@ -121,6 +123,10 @@ def init( log_session_replay_url (bool): Whether to log session replay URLs to the console.
