excel插件| 清单加载在桌面 excel 上显示错误

Question

I have created excel add-ins using office.js and react-fabric UI. I have created manifest and validated using command: npx --ignore-existing office-addin-manifest validate manifest.xml And it looks good with no issue. When I am uploading manifest in desktop excel, it showing below error on excel. Although its not blocking any add ins functionality but it giving wrong impression to user. PFA SS of error: "Error loading add-ins"

On click of Ribbon buttons its working as expected but on excel bottom it showing error on manifest load.

PSB is my manifest file and please help to identify the cause of this error as we need to release application to our customer but because of this error its causing blocker for our releasae.
