What causes "error loading variables: %w" in hashicorp/terraform?

Grant the token's team permission to read workspace variables (or 'Manage Workspaces').

error loading variables: %w

Error message

error loading variables: %w

What it means

In FetchVariables (backend_context.go:206-209), b.client.Variables.ListAll(ctx, remoteWorkspaceID, nil) failed with an error other than tfe.ErrResourceNotFound (404 is explicitly ignored so a workspace with no variables still works). This is the actual variable-list API call failing due to network, auth, server, or permission issues on the variables endpoint.

Solutions

Grant the token's team permission to read workspace variables (or 'Manage Workspaces').
Retry for transient/network errors.
Inspect the wrapped error for HTTP status (403 => permissions, 5xx => server, 429 => rate limit).
Verify the workspace still exists and its ID is current (re-run init).

Defensive patterns

Strategy: retry

Validate before calling

func canListVariables(ctx context.Context, c *tfe.Client, wsID string) bool {
    _, err := c.Variables.List(ctx, wsID, nil)
    return err == nil || errors.Is(err, tfe.ErrResourceNotFound)
}

Try / catch

// Retry non-404 variable-list failures with backoff.
for i := 0; i < 3; i++ {
    vars, err := c.Variables.ListAll(ctx, wsID, nil)
    if err == nil || errors.Is(err, tfe.ErrResourceNotFound) { return vars }
    if !isRetryable(err) { return err }
    time.Sleep(backoff(i))
}

Prevention

Grant the token read access to workspace variables.
Retry transient API errors with exponential backoff.
Inspect wrapped HTTP status to separate permissions (403) from server (5xx).

When it happens

Trigger: Variables.ListAll at backend_context.go:206 returns err != nil && err != tfe.ErrResourceNotFound. Occurs when listing workspace Terraform variables fails for a non-'not found' reason.

Common situations: Token lacks permission to list variables on the workspace. Transient API/network error. TFE variables service degraded. Rate limiting. Workspace ID stale (workspace recreated) so the variables endpoint 500s.
