Expected or Desired Behavior

If there are any Install errors for SPFx App package they should be visible after clicking on errors count on App Details page:

Observed Behavior

After clicking the link the whole content of the page disappears:

Steps to Reproduce

Create some .sppkg that will throw error while installing.
I got that situation trying to deploy Command Set Extension using Feature Framework with RegistrationId="0x01" and RegistrationType="ContentType" (#871)

@AJIXuMuK - Does this still repro? It looks like chrome, can you confirm what browser you are using? Could you please send a fiddler trace of your request clicking on the "1" to grahamc at Microsoft.com?

[AJIXuMuK]

@mcmynn83 all is good now. and yup - it was Chrome.

I'm experiencing the same issue. I tried this in FireFox and Edge, but I get an empty page. Could we reopen this issue?

[GrahamMcMynn]

@samir-farid - could you send a fiddler trace of your call when you click on the 1? That will help us determine why the page isn't loading, we have not been able to investigate it because we haven't been able to repro it.

I'm hitting this same issue... would be great to know what solved it for @AJIXuMuK .

@mcmynn83 - I traced the request in Chrome developer tools and what's happening is it's throwing an Access Denied error behind the scenes - the error comes from 'https://tnubel.sharepoint.com/_layouts/15/AccessDenied.aspx?Source=https://tnubel.sharepoint.com/_layouts/15/appmonitoringerrordetails.ashx?appInstanceId=d236417e-87cd-4a73-923e-9ac12fb20d2e&entryCode=3&lcid=1033&correlation=61b27b9e-00f6-6000-edc2-51d2602b2f52'

Not sure why I'm getting access denied as I'm the site collection administrator and an admin user.

[AJIXuMuK]

@tnubel I believe it was some portion of luck for me :)

[GrahamMcMynn]

@tnubel - Thanks for the access denied URL. I can actually investigate that!!! The reason why you are receiving this error message is that we do a permissions check for the following permissions:
SPBasePermissions.Open |
SPBasePermissions.ViewPages |
SPBasePermissions.AddAndCustomizePages |
SPBasePermissions.ManageSubwebs |
SPBasePermissions.ManagePermissions |
SPBasePermissions.BrowseDirectories |
SPBasePermissions.ManageWeb

The reason you don't have all of those permissions is that AddAndCustomizePages is removed due to noscript being enabled on that site collection. Internally we will discuss if that permission check is really necessary or not.

Thanks,
Graham

I am having this same problem. Is there a workaround here? I am trying to develop an SPFX webpart that provisions and it is erroring out on the install. I can't see what the errors are because of this bug. Is there a log file somewhere else I can look at?

I have an app catalog on my test site collection so I can't seem to monitor the app either.

[AJIXuMuK]

Same issue again, but this time for Add in, not SPFx solution.

[gpeipman]

Same problem here. There is one install error but no way to see it. When I click on link after install error I see popup for a moment and then page goes blank.

[gpeipman]

There is request made to somewhere and it gets redirected to AccessDenied.aspx.

You can avoid the error if you enable custom site scripts. Using the powershell script below you can toggle the setting on/off.

To avoid the error:

Connect-SPOService -Url $tenantUrl
Set-SPOSite -Identity $siteUrl -DenyAddAndCustomizePages $false
Disconnect-SPOService 

To return to default setting:

Connect-SPOService -Url $tenantUrl
Set-SPOSite -Identity $siteUrl -DenyAddAndCustomizePages $true
Disconnect-SPOService
