Solutions

1. Pass --to: `ncl policies set --from <src> --to <dst> --approver <uid>`
2. Verify the target exists via `ncl groups list`

Example fix

// before
ncl policies set --from grp-a --approver telegram:owner
// after
ncl policies set --from grp-a --to grp-b --approver telegram:owner

if (!to) throw new Error('--to required');

When it happens

Trigger: Running `ncl policies set --from <gid> --approver <uid>` without --to; unset variable in a script.

Common situations: Same as other missing-flag errors: copy-paste omissions or empty interpolated variables.
