直接移植到字节小程序的一个问题。

[s2mh]

虽然现在字节小程序还有些功能不完善，但字节对微信小程序的移植提供了很多地支持。Vant 组件通过绝对路径引用也能找得到。我试过几个简单的组件也能正常使用。现在遇到一个问题，在使用 dropdown-menu 和 dropdown-item 时，报错如下

[TMA] TypeError: Cannot read property 'forEach' of undefined at Object.updateChildrenData (universalModuleDefinition:1) at t.tryCatch (tma-core.js:2) at tma-core.js:2 at tma-core.js:2 at Array.forEach (<anonymous>) at t.r.triggerPropObservers (tma-core.js:2) at xc.<anonymous> (tma-core.js:2) at xc.emit (tma-core.js:2) at tma-core.js:2 at Array.forEach (<anonymous>)

[TMA] TypeError: wx.nextTick is not a function at Object.rerender (universalModuleDefinition:1) at t.tryCatch (tma-core.js:2) at tma-core.js:2 at tma-core.js:2 at Array.forEach (<anonymous>) at t.r.triggerPropObservers (tma-core.js:2) at xc.<anonymous> (tma-core.js:2) at xc.emit (tma-core.js:2) at tma-core.js:2 at Array.forEach (<anonymous>)

[TMA] TypeError: Cannot read property 'map' of undefined at Object.updateItemListData (universalModuleDefinition:1) at Object.t [as updateItemListData] (tma-core.js:2) at Object.<anonymous> (universalModuleDefinition:1) at Object.linked (relation.js:45) at t.tryCatch (tma-core.js:2) at t.r.changeRelation (tma-core.js:2) at tma-core.js:2 at Array.forEach (<anonymous>) at xc.<anonymous> (tma-core.js:2) at xc.emit (tma-core.js:2)

dropdown-menu 上显示一片空白。

大家有没有什么思路？
