LEVOAI_COLLECTOR_URL environment variable is required for Le
Error message
LEVOAI_COLLECTOR_URL environment variable is required for Levo integration. Please contact Levo support to get your collector URL.
What it means
Levo integration validation: LEVOAI_COLLECTOR_URL is missing. This URL is the OTLP HTTP endpoint events are POSTed to and is customer-specific (one per Levo tenant), which is why the message tells you to contact Levo support. Without it, no endpoint exists and exporter construction fails.

Solutions
- Obtain your collector URL from Levo support and export LEVOAI_COLLECTOR_URL=https://<your-tenant-collector>
- Confirm the URL matches exactly what Levo provided (it is used verbatim)
- Set it alongside the other three LEVOAI_* vars in the deployment env
- Until provisioned, disable the levo callback to keep the proxy bootable
Example fix
# before # LEVOAI_COLLECTOR_URL unset -> ValueError ... contact Levo support # after export LEVOAI_API_KEY=... export LEVOAI_ORG_ID=... export LEVOAI_WORKSPACE_ID=... export LEVOAI_COLLECTOR_URL=https://collect.mycompany.levo.ai
Defensive patterns
Strategy: validation
Validate before calling
import os
def levo_config_valid() -> bool:
return bool(os.getenv("LEVOAI_COLLECTOR_URL")) Prevention
- Complete Levo collector provisioning before enabling the callback
- Add a connectivity preflight: issue an HTTP request to the collector URL at startup
When it happens
Trigger: levo callback enabled with the other three vars set but no LEVOAI_COLLECTOR_URL; URL present in a local .env but not loaded in the container; a placeholder value that was never replaced.
Common situations: New Levo customers who have keys/org/workspace but have not completed collector provisioning (Levo support supplies the URL); environments where only the generic Levo doc vars were set.
