Error message

answers[${entry.index}].answer selected value is not in the option schema: ${selectedValue}

What it means

For option-kind answers the single selected value must be one of the question's option values. This is the single-select counterpart of the schema membership check and carries code question_invalid_answer.

Solutions

1. Map UI choice to question.options[].value before submit
2. Refresh the question schema if options may have changed since render

Example fix

// before
answer.selected_values = [selectedLabel];
// after
answer.selected_values = [question.options.find((o) => o.label === selectedLabel)!.value];

const known = new Set(question.options.map((o) => o.value));
if (answer.kind === 'option' && !known.has(answer.selected_values[0]!)) throw new Error('value not in schema — remap from fresh schema');

function valueInSchema(q: NormalizedQuestionItem, v: string): boolean { return q.options.some((o) => o.value === v); }

try { await submit(p, answers); } catch (e) { if ((e as Error & { code?: string }).code === 'question_invalid_answer' && /not in the option schema/.test((e as Error).message)) { await remapValuesFromFreshSchema(); return submit(p, answers); } throw e; }

When it happens

Trigger: kind 'option' where selected_values[0] is not in optionValues — e.g. a label, a sentinel, or a value from an outdated schema.

Common situations: Submitting labels instead of values; stale client schema after options changed; hand-crafted payloads in scripts/tests with guessed values.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
