Plan isn't archived

Error message

Plan isn't archived

What it means

UnarchivePlanHandler rejects unarchiving a plan whose archived_at is NULL, returning HTTP 400 "Plan isn't archived". It's a state guard ensuring unarchive only applies to plans that are currently archived.

Solutions

1. Fetch the plan first and skip unarchive if archivedAt is null (treat 400 as already-done)
2. Disable the unarchive action in the UI for non-archived plans
3. Don't auto-retry this 400 — it's a permanent state conflict
4. If unarchiving is genuinely needed, it means state changed elsewhere; refresh plan data

Example fix

// before
await unarchivePlan(planId);
// after
const plan = await getPlan(planId);
if (plan.archivedAt) await unarchivePlan(planId);

const plan = await getPlan(planId);
if (!plan.archivedAt) { /* not archived, nothing to unarchive */ return; }
await unarchivePlan(planId);

function isArchived(v) { return v != null; } // archivedAt non-null means the plan is archived
if (!isArchived(plan.archivedAt)) skipUnarchive();

try { await unarchivePlan(planId); } catch (e) { if (e.status === 400 && e.message === "Plan isn't archived") return; /* treat as success */ throw e; }

When it happens

Trigger: Calling the unarchive endpoint for a planId whose archived_at is NULL — the plan was never archived or was already unarchived.

Common situations: Double-clicking an unarchive button; concurrent unarchive by another session; retrying a request that already succeeded; scripts that unarchive unconditionally on startup.
