Using App registration instead of legacy service principal results in SharePoint Add-in installation error (The operation took too long)

Question

Using App registration instead of legacy service principal results in SharePoint Add-in installation error (The operation took too long)

fredj-6392 1

Hi,

I am currently using MSOnline Powershell module (New-MsolServicePrincipal) to register an app, so SharePoint Add-in can be added and installed on the tenant afterwards. This mimics app registration through AppRegNew. aspx. Since MSOnline module is getting deprecated, and ServicePrincipalType that is getting created is Legacy, I am trying to use other modules to register an app. Currently I am using Azure Az module (New-AzADApplication and New-AzADServicePrincipal) to create an App Registration and Service Principal associated with it.

The issue I have now is that when I am trying to install SharePoint Add-in, installation fails with the ‘The operation took too long.’ error:

Creating app registration together with service principal manually through Azure AD gives the same result, but if creating it through AppRegNew .aspx everything works properly. If someone has encountered this before or knows what the issue might be I would appreciate any help.

Hi @fredj-6392 ，
Per my test, I will get the same error register app with Service Principal and it fixed with the app registered in AppRegNew .aspx.

After research some document. I will recommend to create it through AppRegNew .aspx like following document

Thank you for your answer (and for confirming that you get the same error), @RaytheonXie_MSFT , creating app registration through AppRegNew .aspx works indeed, however, what I am trying to focus on is automation, without any manual steps. I am able to create the same app registration using PowerShell MSOnline module, but since it is getting deprecated I am looking for an alternative. Current modules utilize Microsoft Graph API and create a different type of app registration and service principal, which results in the previously mentioned error. Are you aware of any other ways we could register app automatically?

Hi @fredj-6392 ，
As far as I know, we are unable to register app automatically by AppRegNew .aspx. You can try to register it by program as a workaround

Hi,

Not sure about the issue part but I have noticed that you can't specify domain while registering an app in azure portal whereas it's possible from AppRegNew.aspx. You will not require domain for any background process however if you are creating a provider hosted add-in, it is needed.
