Troubleshooting
Common issues and how to resolve them
Quick Diagnostic Checklist
Build Errors
Build fails with "Module not found"
A required Python package is not listed in requirements.txt
Add the missing package to your requirements.txt file and rebuild the agent.
Build fails with syntax error
Invalid Python syntax in agent code
Check your code for syntax errors. The error message will include the line number.
Build times out
Large dependencies or slow network during package installation
Try removing unused dependencies. Contact support if the issue persists.
Deployment Issues
Agent stuck in "deploying" status
Deployment process is taking longer than expected
Wait a few minutes. If status doesn't change, try redeploying.
Cloud agent not connecting
Chrona Worker is not running or misconfigured
Ensure the Chrona Worker is running and properly configured with your API key.
"Worker not available" error
No worker is registered to handle this agent type
For Cloud agents: start your Chrona Worker. For Secure agents: redeploy.
Execution
Execution stuck in "pending" status
No available worker to process the task
Check that the agent is deployed and workers are healthy.
Task fails with timeout
Agent execution took longer than the configured timeout
Increase the timeout in endpoint settings or optimize your agent code.
Input validation error
Provided inputs don't match expected types or are missing required fields
Check that all required inputs are provided with correct types.
"Agent not found" error
The referenced agent/endpoint doesn't exist or isn't deployed
Verify the agent exists and is in "deployed" status.
Volt (Slack)
Slack user cannot message the bot
User is not a member of the ViksaAI project linked to the runtime
Add the user to the project in org settings. Their Slack email must match their ViksaAI account.
Credential validation fails
Missing bot scopes, Socket Mode app token, or incorrect signing secret
Regenerate the manifest from the Volt panel and recreate the Slack app, or add scopes shown in the validation report.
Runtime pod not running
Kubernetes deployment failed or was scaled to zero
Open Volt → Slack status. Resume the runtime or check cluster logs for volt-engine-service.
Authentication
Token refresh fails
Refresh token has expired or been invalidated
Log out and log back in to get new tokens.
SSO login fails
SSO configuration is incorrect or certificate has expired
Check SSO settings and verify IdP configuration matches.
"Unauthorized" error on API calls
Access token is expired or invalid
Ensure you're using a valid access token. Refresh if needed.
