A member of [`ProblemCode`](../api/ProblemCode.md) · stable · since 2.0.0

[`boot`](../api/boot.md) got an option this contract doesn't have; it was ignored.

## What to do

[`boot`](../api/boot.md) takes only `el`, `accountId`, `configuratorId`, `contract`, `document` and `signal` ([`BootOptions`](../api/BootOptions.md)): move the option's value into a member call after boot (camera, stage, document) or into [`BootOptions.document`](../api/BootOptions.document.md).

## Where the declaration names it

- [`boot`](../api/boot.md): Errors: rejects HoloInputError on bad options; an unknown option records 'unknown-boot-option'; rejects HoloBootError (`reason`) when the renderer can't start, and at once, before any document request, when the browser has no WebGL 2.

The set is open: handle a code you don't know (`'other'`).
