Hex Common Errors

Error Reference

401 Unauthorized

Cause: Token invalid, expired, or missing. Fix: Regenerate token in Hex workspace settings.

403 Forbidden — Read-Only Token

Cause: Token has "Read projects" scope but RunProject requires "Run projects". Fix: Create new token with "Run projects" scope.

404 Not Found — Project

Cause: Project ID wrong or project not published. Fix: Verify project ID. Only published projects can be run via API.

429 Too Many Requests

Cause: RunProject is limited to 20 requests/min, 60/hr. Fix: Queue runs with delays. See hex-rate-limits.

Run Status: ERRORED

Cause: SQL query, Python code, or connection error in the project. Fix: Open the project in Hex UI and check the error in the run history.

Run Status: KILLED

Cause: Run exceeded timeout or was manually cancelled. Fix: Optimize slow queries. Increase timeout in API trigger.
