This looks like the bug I've fixed yesterday. When you've enabled page transformation for a site did you use the same casing for the URL as the URL actually is shown in SharePoint. There's a string replacement that used to fail when not being case sensitive.

Two ways to fix (both should work)

• Drop the latest solution from dev tree (https://github.com/SharePoint/sp-dev-modernization/blob/dev/Solutions/PageTransformationUI/assets/sharepointpnp-pagetransformation-central.sppkg) in the app catalog and then go to the modernization center -> site contents -> click on the three dots next to the sharepointpnp-pagetransformation-central app and click on "Get it" to install the latest version in the modernization center site
• Use the web part in the modernization center and disable page transformation for your site and then re-enable it using the url written in the correct casing

Also can you please share the output of Get-PnPStorageEntity and check for any red error message in the browser debug console (press F12 on the page that hangs).

Hey @derLarsonaut ,

Can you check some more things:

• Did you get errors while provisioning the function? If you used upper case characters in the older versions of the script then this could result in errors when configuring the function app. If you go check the web settings of the function app and don't see properties like CLIENT_ID and CLIENT_SECRET then this needs to be corrected
• Go to https://http://aad.portal.azure.com, click on "Azure Active Directory", click on "App registrations", type in SharePoint and set the drop down to "All Apps". Click on "SharePointPnP.Modernization", click on "SharePointPnP.Modernization" underneath "Managed application in local directory", click on "Permissions". You should see 2 admin consented permissions, if that's not the case then the admin consent step was not yet done. You can do that then by clicking on the "Grant admin consent for..." button
• Third thing to check is if the permission was correctly granted, if the previous step is not done then this might have failed as well. Please run Get-PnPTenantServicePrincipalPermissionGrants and verify there's a permission returned with Resource = "SharePointPnP.Modernization" and Scope = "user_impersonation". If you don't see this permission grant then please run Grant-PnPTenantServicePrincipalPermission -Scope "user_impersonation" -Resource "SharePointPnP.Modernization"

I'm currently writing a troubleshooting guide and have already improved the Azure setup process, but the permission grant in Azure stays a manual thing. Thanks for testing and let me know if this gets you unblocked. If not then let's set a quick call to verify things.

Hi @derLarsonaut,

I've created a troubleshooting guide over here: https://github.com/SharePoint/sp-dev-modernization/blob/master/Solutions/PageTransformationUI/docs/troubleshootingguide.md

Not sure if you still see the error, but that guide will help you troubleshoot the issue.

Hi @jansenbe Thanks a lot for your time.
I found the problem. The deploy of the service binaries to the azure function app was not successfull. I tried it again via Kudu and know it works!

Good news @derLarsonaut.

Any idea why it failed in the first place? Did you use the setup script or did it manually? Any errors from that process that you recall?

from modernization.

@jansenbe I followed this page: https://github.com/SharePoint/sp-dev-modernization/blob/master/Solutions/PageTransformationUI/docs/manual%20setup/modernization-ui-manual-azure.md
I probably didn't read the message correctly after uploading via kudo.
