This is not a PnP issue per se. The underlying APIs we use to provision Modern team sites backed by O365 group dont allow provisioning with App-only credentials.

It will work with user credentials. Ensure that you are a Global Admin as well.

Connect-PnPOnline –Url https://tenant.sharepoint.com –Credentials (Get-Credential)

After that you can use the New-PnPSite commandlet to provision the modern team site.

@gautamdsheth : Yes gautam . I have already created my sitecollection using user credential. but my requirment is not with user account that is why i didn't mention about that in my issue.

I have to create site using app id secret as we are doing earlier in sharepoint.
Please suggest me on same and if it is not possible then please comment on that with the exact microsoft terms

There is a uservoice item for this:
https://sharepoint.uservoice.com/forums/329220-sharepoint-dev-platform/suggestions/34236700-ability-to-use-app-only-calls-to-create-modern-sit

At 13 juni the uservoice item has been marked as 'Boom! It's done'.

Can we have a timeline when we will be able to use this feature in pnp? Is this days/weeks/months?

Given that the upstream issue in the Sharepoint API was corrected on June 13, 2019 are there changes still required to support it in the Sharepoint PnP Powershell module? Is this work planned?

[advdberg]

I think the fix mentioned on the 13th of june is only applicable on the modern sites without a Group/Team connected to it and not on the modern Teamsites with a Group/Team connection, they are
created using different REST api's on the background, the /_api/GroupSiteManager/CreateGroupEx still doesn't support App-only unfortunately.
