Introduction
This article describes how to troubleshoot the SIC-001 error in Terraform Cloud when a workspace fails during the configuration retrieval phase in a VCS-driven workflow.
Problem
When Terraform Cloud fails to fetch your configuration from the connected VCS repository, you may see this error:
Error: failed to retrieve configuration
Internal error: SIC-001.
Failed to ingress entity: AgentJob for workload cv-xxxxxxxxx encountered an error.
This prevents Terraform Cloud from retrieving your configuration and starting a run.
Possible Causes
This error occurs when Terraform Cloud cannot successfully create or ingest a configuration version from the connected VCS repository.
Common causes include:
Temporary VCS outage or API disruption
Expired or insufficient VCS access token
Repository access or permission changes
Repository renamed, moved, or deleted
Stale or partially ingested configuration version (especially after an outage)
Webhook delivery failure or delay
Transient backend ingestion issue
Solutions
1. Trigger a new configuration version (recommended)
Push a no-op commit to force Terraform Cloud to recreate the configuration version.
2. Verify VCS connection
Confirm the repository is accessible
Ensure OAuth/App authorization is valid
Verify the correct repository and branch are configured
3. Re-authenticate the VCS provider
If credentials were recently rotated or expired:
Go to Terraform Cloud → Settings → VCS Providers
Reconnect or re-authorize the integration
Re-link the workspace if necessary
4. Check VCS provider status
Review your VCS provider status page for:
Service outages
API rate limiting
Degraded archive download performance
