The private_link_fast_path_enabled was introduces since v3.100.0 #25596 , which appears to have introduced this issue.

I get this same error even with the most basic config, so changing "enable_internet_security" might just be coincidental.

This is still true for AzureRM version 4.5.0
Here is the error output message:

This is same issue as reported here, but it was not fixed in v3.116. I tested v116 as well and showing the same error

I temporarily remove private_link_fast_path_enabled as a workaround in my env as a workaround. This property does not seem to be supported by the service
