[Medium] mergeSnapshotOptions requires a newer @percy/sdk-utils than the pinned range

utils.mergeSnapshotOptions was only added to @percy/sdk-utils in 1.32.0-beta.9, but package.json pins @percy/sdk-utils: ^1.0.0. An environment resolving an older 1.x sdk-utils satisfies the range yet lacks this export, so this line throws TypeError: utils.mergeSnapshotOptions is not a function and the snapshot is silently swallowed by the surrounding catch.

Suggestion: Bump the minimum @percy/sdk-utils to the version that ships mergeSnapshotOptions (e.g. ^1.32.0), or guard the call: const mergedOptions = utils.mergeSnapshotOptions?.(options) ?? options;

Reviewer: stack:code-review

/* istanbul ignore next: no instrumenting injected code */
let { domSnapshot, url } = await nEval(options => ({
/* eslint-disable-next-line no-undef */
domSnapshot: PercyDOM.serialize(options),
url: document.URL
}), options);
}), mergedOptions);

No test coverage for this? is it covered in the existing UTs?


// Post the DOM to the snapshot endpoint with snapshot options and other info
