关于鸿蒙版使用weboffice保存失败问题（安卓正常），求助，急

发送的不为空，错误信息是instance.save报的错，走到catch之后，h5Port.postMessage发送的result是一个错误类，鸿蒙侧接受的时候说类型不匹配，但这应该也是postMessage发送成功了， instance.save是调用的wps的方法，这个会不会跟鸿蒙不适配，安卓调用的时候不会报错 ，调用报错如下：Uncaught (in promise) DOMException: Failed to execute 'postMessage' on 'Window': Invalid target origin '' in a call to 'postMessage'. at e.sendMsgToWps (https://ai-ppt.camoryapps.com/js/web-office-sdk-solution-v2.0.5.umd.js:1:24650)

看着这错误都像是sdk里的
