Picking a suggestion under "Tidigare motparter" in Bokför transaktion replaced
the page with "Något gick fel". handleOpenTemplateReview built the review state
from `{ id, name_sv } as BookingTemplate`, so `template.debit_account` was
undefined, reached QuickReviewDialog's required `defaultAccount: string`, and
threw on `accountOverride.startsWith('2')` during the first render.
Typed the dialog's template prop as a narrow ReviewTemplate whose optional
fields are actually optional, so the cast disappears and the compiler owns this
class of bug. Also carries the counterparty's learned accounts and VAT (the
preview showed the category fallback, not what the server books) and decides
"is this a counterparty booking" from the template id rather than the presence
of a line_pattern (single-line templates got an account/VAT editor the
categorize route discards).
Five more page-crashes of the same shape, adversarially verified:
- suppliers/[id] and supplier-invoices/[id] passed the error envelope OBJECT as
a toast description. The Toaster is a sibling of {children} in the ROOT
layout, so that throw escapes both segment error boundaries onto global-error.
- components/reports/views wrote the same object into a useState<string | null>
at 13 sites and rendered it bare.
- components/ui/toaster.tsx now coerces non-renderable values as a choke point.
- skattekonto read data.informationstext.length off Skatteverket's raw JSON,
where the field is not required.
- TicWorkspace read profile.statuses.length off a persisted jsonb blob. 17 of 17
prod rows predate the TIC v2 upgrade (#584) and lack the key, so that
workspace was in the error boundary for every company that had opened it.
Plus hardening: formatCurrency coerces a null currency to SEK (prod has 0 NULL
across 28 416 transactions, so defense not a live bug) and cleanSignatory
returns [] for a missing description.
Verified by rendering the real dialog against a throwaway /sandbox route: the
pre-fix prop shape reproduces the exact error boundary, the fixed one renders
D: 6570 Bankavgifter / K: 1930 Företagskonto and the matching verifikat.
No migrations.
Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.
Website · Hosted app · Documentation
Why Accounted?
Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
Agent-native. The full bookkeeping engine is exposed as 100+ MCP (Model Context Protocol) tools with scoped API keys, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.
Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.
