AFFECTSRootCause

add a new schema for the login — And picking only the email and password from FormType in loginService. Outcome: LoginFormSchema = z.object({ email: z.string().email(), password: z.string().min(8, { message: 'Must be 8 or more characters long' }), }).

AFFECTSRootCause

`superRefine()` was never reached because a `z.enum(...)` field failed earlier validation due to initial/default values (e.g., an empty string). Zod stops at earlier schema errors, so later refinements don’t run.

AFFECTSRootCause

Setting defaultValue={undefined} also triggers similar issues. — the number input field. Tension: Using an empty string "" as the default value isn’t feasible because the input expects a number type. Outcome: the failure to coerse the default value `''` to a number will trigger one of the error messages above.

A React Hook Form + Zod form with a ShadCN number input triggers controlled/uncontrolled state warnings and type mismatches when the number field lacks a proper default value (undefined or empty string). Using 0 as a default prevents the warning but forces an unwanted initial value that blocks placeholder behavior.

AFFECTSRootCause

const zodField = get(schema?.shape, zodFieldPath); if (!zodField) handleNotFoundField(fieldName); return zodField instanceof ZodOptional; — schema written in zod. Outcome: return zodField instanceof ZodOptional.

AFFECTSRootCause

it takes about 0.5 seconds for the useSession to update the session — default within useForm hook. Outcome: useEffect() hook of react.

AFFECTSRootCause

the value changing from undefined to a defined value — changing the `text` (username) input value. Tension: which should not happen.

AFFECTSRootCause

Zod/Fastify request parsing and validation (and/or body parsing) altered the request payload before it reached the route handler.

AFFECTSRootCause

path: ["start_time"] — .refine((val) => dayjs(val.start_time).isBefore(dayjs(val.end_time)). Tension: validation specifically for the `end_time` field. Outcome: Specify the path to show the error on the end_time field.

REQUIRESSolution

The solution I found is to add a new schema for the login. — loginService. Tension: picking only the email and password from FormType in loginService. Outcome: And picking only the email and password from FormType in loginService.

REQUIRESSolution

Align the schema to the actual data shape (e.g., use `z.array(z.object(...))` for `templateDefaults`) and/or override Zod’s default `invalid_type` message using an `errorMap` on the relevant Zod type so trigger() receives the custom message.

REQUIRESSolution

Create useFieldOptionality hook — Pass zod schema. Tension: Field ${fieldName} not found in schema. Make sure the field exists in the schema or do not pass the schema inside the Form. Outcome: return zodField instanceof ZodOptional.

PERTAIN_TOProblem

A React Hook Form + Zod form with a ShadCN number input triggers controlled/uncontrolled state warnings and type mismatches when the number field lacks a proper default value (undefined or empty string). Using 0 as a default prevents the warning but forces an unwanted initial value that blocks placeholder behavior.

PERTAIN_TOProblem

I want to use Zod to validate dat — I'm building a Next.js application with TypeScript and Supabase as my backend. Tension: Supabase CLI automatically generates TypeScript types from my database schema. Outcome: This isn't ideal but has helped me and ensures that everything is typed which helps with the errors and maintenance.
