# 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.
