FAQ

A list's scroll position never changes in Replay playback

Replay can only record areas whose scrolling reaches the logic layer: page scrolling, ScrollView (scroll-view) and Swiper paging. A WeChat view with CSS overflow: auto / overflow: scroll dispatches no scroll events to the logic layer, so the SDK cannot see its scroll position and playback stays at the area's initial position.

This usually happens with third-party components, such as tables, that scroll inside a View with CSS overflow. Scrolling in such areas is missing from Replay; the rest of the recording is unaffected.

To replay scrolling in such an area, make the scroll container a ScrollView:

import { ScrollView } from '@tarojs/components';

<ScrollView scrollY style={{ height: '100%' }}>
  {/* content previously inside the overflow container */}
</ScrollView>;

If you cannot change the component's internals, let the page scroll instead of the component. This is a platform limitation, not a feature that needs extra configuration.

Errors from WeChat DevTools are not symbolicated

DevTools loads the local build from http://127.0.0.1:<port>/appservice/…, which is not the code the final WeChat maps uploaded to Sentry describe, and the SDK does not rewrite these frames. Verify symbolication on a trial or release build; see Taro build plugin.
