Can't ask approval for state migration when interactive…

Error message

Can't ask approval for state migration when interactive input is disabled.

Please remove the "-input=false" option and try again.

What it means

`promptMultiToSingleCloudMigration` returns this when collapsing a multi-state backend into a single cloud workspace needs a confirmation but input is disabled (`m.input == false`) and `-force` is not set. This path is lossy by nature (multiple workspaces -> one), so Terraform insists on explicit consent.

Solutions

Reconsider the migration: multi->single is destructive; instead target a `cloud` block that preserves separate workspaces.
Run interactively (drop `-input=false`) and confirm you accept the consolidation.
If intentional, pass `-migrate-state -force` and verify the surviving state afterward.

Defensive patterns

Strategy: validation

Validate before calling

// Before multi->single cloud migration:
if !m.input && !opts.force {
    return errors.New(strings.TrimSpace(errInteractiveInputDisabled))
}

Prevention

Avoid multi->single migrations; they are destructive — restructure the cloud block to keep multiple workspaces.
If unavoidable, confirm explicitly and back up state first.
Never run this path silently under `-input=false`.

When it happens

Trigger: `terraform init` migrates from a multi-state backend (e.g. `backend "remote"` with multiple named workspaces) into a single cloud workspace, `m.input == false`, `opts.force == false`.

Common situations: Consolidating workspaces during a backend refactor in CI; the multi->single reduction can drop states and Terraform will not do it silently.
