API management (admin) - [Version]:16.0.0.8901 - Another object with the same value for property identifierUris already exists.

Expected or Desired Behavior

After creating a SPFx solution that needs to access Microsoft Graph, I wanted to go to admin portal to approve permissions

Observed Behavior

I initially had something similar to #3823 (permission entry already exist), but then I got something different with no clue how to fix it

error: {code: "-1, Microsoft.SharePoint.Client.UnknownError", message: "Unknown Error"}

I get the following messages on the central admin page

And I can't see any of the app permission requests that are supposed to appear with my SPFx packages...

Steps to Reproduce

Whatever I can try now I always get this unknown error message on the app permissions page

Could you please help with this ?

Regards,
Yannick

We are having the same issue since a few days.

Before we did have the Error "Another object with the same value for property identifierUris already exists."

Exactly @mirkori , I'm more confident since I'm not alone :D

Actually I got the "Unknown Error" because I tried to remove multiple entries in the Azure AD after I saw this message.

I restored them using the AzureAD Powershell and now I get back the same message

I checked on another brand new developer tenant and I get exactly the same issue

Same issue here. Also is weird that I´m seeing 2 Azure Ad Apps registered as "SharePoint Online Client Extensibility Web Application Principal"

[ypcode]

I see it 6 times

Actually my SPFx app specifies 3 permission requests, and I deployed it two times... I really suspect it is related to that...

[luismanez]

Seems so! I always thought there should be only one App registered that way for all the spfx solutions using aadHttpClient...

[ypcode]

It looks like it is what the error message says somehow...

I edited the title since the real issue is really this one...

Can confirm same issue on multiple tenants.

[ypcode]

Exactly the same issue on my two dev tenant and my prod tenant

Same issue.

My workaround was to view the console when running my SPFx webpart and found out what clientId it was trying to call. Then deleted all the duplicates except the one that my webpart was actually using. Waited about 15 min and i got it working.

Have the same issue - resulting in my webparts throwing the error
