I have deployed a SPFx Extension solution to my site.

Everything went well except the Extension sometime loads, sometimes doesn't. In another word, if I refresh it a few times then sometime it won't work.

All I got in the browser console when it doesn't work is:

Failed to create application customizer 'ClientSideExtension.ApplicationCustomizer.6998cb93-00a1-46a6-a00b-786fd612c706'. Error information is '***Manifest not found for componentId "6998cb93-00a1-46a6-a00b-786fd612c706".'

I know the manifest is there since it's working with some refresh. The scripts are deployed into our CDN in the same site collection.

enter image description here


<Elements xmlns="http://schemas.microsoft.com/sharepoint/">    
<!-- Custom Action -->
    ClientSideComponentProperties="{&quot;Top&quot;:&quot;Top area of the page&quot;,&quot;Bottom&quot;:&quot;Bottom area in the page&quot;}">
<!-- End Custom Action -->

Can someone know what cause this ? Thanks,

    make sure you have the correct versions of tools. This was a bug a while back but has been fixed: github.com/SharePoint/sp-dev-docs/issues/632 – Ali Jafer Oct 9 '17 at 11:01
  • can you also share the elements.xml file ? Did you reference that file correctly in the ` package-solution.json` file ? – Gautam Sheth Oct 9 '17 at 12:47
  • @AliJafer: I'm running latest SPFx 1.3 but I'll check tmr to see if it's updated or anything else is outdated. – Thi Vo Oct 9 '17 at 16:38
  • @GautamSheth: I will post it tmr. But if it's incorrect then it shouldn't work at all. Not like this. This is weird T_T – Thi Vo Oct 9 '17 at 16:40
  • @AliJafer: I updated the @types/sharepoint to latest version and things seem to work normally again (the types was update 3 days ago) – Thi Vo Oct 10 '17 at 4:01

Update @types/sharepoint into 2016.0.0 fix it.
