Resolved 65 type errors across the codebase via these v4 migration
patterns:
- `ZodError.errors` renamed to `ZodError.issues` (4 call sites in auth
routes + central error handler).
- `z.record(value)` now requires explicit key type: `z.record(z.string(),
value)`. Updated 7 sites across templates / forms / saved-views /
website-inquiries.
- `.refine(check, msgFn)` second-arg shape changed — now requires an
`{ error: (issue) => ... }` object form. Updated
`mergeFieldsSchema` in document-templates validator.
- `.transform(...).default(...)` chains: v4 enforces default value type
matches transform OUTPUT. Reordered to `.default(...).transform(...)`
in list-query / company-memberships handlers.
- `z.coerce.*()` INPUT type widened to `unknown` in v4. Service signatures
using `z.input<typeof schema>` (kept for caller flexibility around
defaults) now re-parse via `schema.parse(data)` to recover the
post-coercion shape Drizzle needs. Done in berth-reservations service.
Invoice service narrows `lineItems` locally with a typed cast since
re-parsing would double-validate.
- `.optional().transform(...)` no longer propagates the optional marker
through v4's new ZodPipe. Moved `.optional()` to the END of chain in
`optionalDesiredDimSchema` (interests) and documents list query
(folderId, signatureOnly).
- ZodIssue subtype shapes simplified: `received` removed from
invalid_type, `type` renamed to `origin` on too_small. Test fixtures
updated.
- @hookform/resolvers v5 splits Resolver into 3-generic form (Input,
Context, Output). useForm calls in 6 forms (client, yacht, berth,
interest, expense, invoices-new-page) now pass explicit generics:
`useForm<z.input<typeof schema>, unknown, z.infer<typeof schema>>`.
Verified: tsc clean (0 errors), vitest 1293/1293 pass.
