Error message
The "freeze" prop of <Sequence /> must be a number, but is of type ${typeof freeze}. What it means
Thrown when the freeze prop of <Sequence> is defined (not undefined/null) but is not a number. freeze pins playback at a specific frame, so a non-number makes the freeze point indeterminate.

Solutions
- Pass a concrete frame number: freeze={30}.
- Coerce when reading from external sources: freeze={Number(rawFreeze)}.
- Omit freeze entirely when freezing is not desired, rather than passing a sentinel.
Example fix
// before
<Sequence freeze={config.freezeFrame} />
// after
<Sequence freeze={config.freezeFrame ? Number(config.freezeFrame) : undefined} /> Defensive patterns
Strategy: type-guard
Validate before calling
const freeze = typeof rawFreeze === 'number' ? rawFreeze : undefined;
Type guard
const isFreezeFrame = (v: unknown): v is number => typeof v === 'number' && Number.isFinite(v);
Prevention
- Pass freeze only when you actually want to pin a frame.
- Avoid boolean or string sentinels for the freeze prop.
When it happens
Trigger: Passing freeze="10" (string), freeze={true}, freeze={someObject}, or any non-number truthy value to <Sequence>.
Common situations: Loading freeze from config as a string; conditional freeze={condition} where condition is boolean instead of a frame number; mis-spelling a related prop.
