Is extension attribute supported during Create Provisioning Policy for Azure AD connector?

Hi team,

We’ve an extension attribute - "extension_<clientID>_<CustomAttributeName>" in our Azure AD B2B that we want to read/write from SailPoint as part of aggregation and new account provisioning processes.
I’ve added this attribute under Account Schema of AzureAD connector and we are successfully able to read this attribute as part of aggregation.

Problem is on the second part where we are not able to provision this extension attribute during new account provisioning process (I’ve already added the extension attribute on the Create Profile). We’re getting below error -

As per one of the SailPoint AzureAD source documentation, it says extension attribute provisioning is supported -

Any leads on the error “Invalid type of property” or how to properly include “extension attribute” in Create Provisioning policy?
TIA!

I’ve figured out the issue which is what the error flags out “incorrect type of property” for the extension attribute.
This is resolved, thanks!
