Failed to load state manager: %w

Error message

Failed to load state manager: %w

What it means

Wrapped error from getStateFromBackend when b.StateMgr(workspace) returns diagnostics with errors. This builds the state manager for the resolved workspace against the configured backend; diagnostic errors mean the backend could not initialize its state store (e.g. S3 bucket absent, cloud auth failed, local state path unwritable). 'terraform show' (no path) then has no state to display.

Solutions

  1. Run 'terraform init' to reconfigure the backend and surface auth/config errors.
  2. Verify the state resource (bucket, object key, cloud workspace) exists for the configured backend.
  3. Confirm credentials (AWS_*, TF_TOKEN_*, TF_CLOUD_*) are valid and have access.
  4. Check the wrapped diagnostic for the backend-specific cause.

Example fix

// before
$ terraform show
Failed to load state manager: ...
// after
$ terraform init
$ terraform show
Defensive patterns

Strategy: validation

Validate before calling

// Pre-flight: confirm backend resource reachability before 'terraform show' (no path)
package main

// (S3 illustration) confirm the state object exists
func preflightStateObject(bucket, key, region string) error {
	sess := session.Must(session.NewSession(&aws.Config{Region: &region}))
	_, err := s3.New(sess).HeadObject(&s3.HeadObjectInput{Bucket: &bucket, Key: &key})
	if err != nil { return fmt.Errorf("state object unreachable: %w", err) }
	return nil
}

Prevention

When it happens

Trigger: Running 'terraform show' with no path when the backend fails to construct a state manager for the current workspace — missing bucket/object, invalid credentials, non-existent cloud workspace, or local state file I/O error.

Common situations: Backend credentials expired; S3 state object/bucket deleted; cloud workspace renamed/deleted; local state file locked or permission denied; region/endpoint misconfiguration; backend not yet initialized ('terraform init' not run).
