Hi @LijuV-MSFT apologies for the inconvenience. This issue will be resolved in the next release.

[LijuV-MSFT]

Thank you, @timayabi2020

I am also seeing the same error using update-MgPolicyTokenLifetimePolicy. Any idea when this will be fixed?

Hi there, i am also having the same issue, even with following the example given here:
https://learn.microsoft.com/en-us/entra/identity-platform/claims-customization-powershell

Is there a work around? and when is the fix expected?

thanks

also seeing this issue in 2.26.1 - which was needed because of the issues in 2.26.0. are we going to get a fix for this issue any time soon as its a blocker in a pipeline task? or a working workaround with example rather than just "use the graph api"?

[LijuV-MSFT]

@RollsChris / @SeanBintleyThrive

One workaround is to use install the previous vesions

Install-Module Microsoft.Graph.Authentication -RequiredVersion 2.25.0 -Force
Install-Module -Name Microsoft.Graph.Identity.SignIns -RequiredVersion 2.25.0 -Force
Install-Module Microsoft.Graph.Applications -RequiredVersion 2.25.0 -Force

You may need to uninstall the latest version first.

any news on this? also does anyone know if you can mix and match beta and v1 calls?
i seem to have gotten our app into a state, I'm getting this error and i think its because i have been trying different things out the different versions.

[invalid_request] AADSTS1100001: Non-retryable error has occurred. Underlying error code: 1003016. AADSTS1003016: The appId of the custom extension resourceId should correspond to a real service principal in the tenant.

im also seeing this at the top of the page like things have got out of sync:

Thanks
