Failed to load state

Error message

Failed to load state: %s

What it means

After resolving the workspace, OutputCommand retrieves the state manager via b.StateMgr(env). If the returned diagnostics have errors, this message wraps diags.Err() and aborts. This is a backend-layer failure accessing the state store for the chosen workspace, not a state-decode failure.

Solutions

1. Run terraform init to reconfigure the backend after any backend block change.
2. Verify credentials, endpoints, and permissions for the state backend (e.g. AWS creds with s3:GetObject on the state key).
3. Ensure the lock table / KV path referenced by the backend still exists.
4. Inspect diags.Err() in the %s for the backend-specific failure reason.

Example fix

# before: state backend auth fails
terraform output
# after: refresh creds + reinit
export AWS_PROFILE=state-read
terraform init
terraform output

// Probe backend state access before the command.
if _, d := b.StateMgr(env); d.HasErrors() {
    return fmt.Errorf("state backend unavailable; check creds and run 'terraform init': %s", d.Err())
}

When it happens

Trigger: b.StateMgr(env) returns sDiags with HasErrors() true — e.g. the backend cannot authenticate to the state bucket, the configured state backend is invalid, or the workspace key prefix is malformed.

Common situations: S3 remote state with missing/revoked AWS credentials; DynamoDB lock table removed; Consul/HTTP backend endpoint unreachable; backend block reconfigured without terraform init; workspace state object deleted out-of-band.
