Hi Jcook,
I add flows to site in my developer environment in the past 2 months with no issues. I only had this issue since last Friday.
I even tried testing this on a new environment with no custom solutions installed, just the standard power pages package. One thing I found out is that when adding flows on a standard data model site, it's ok. However, when I tried to add flow to a enhanced data model site, then this error comes up. I have tried testing this on various environments and they all had the same issue.
Not sure if it's something to do with the latest release. I've raised a ticket with Microsoft, waiting to hear back from them.
Are there any ones having similar issues?
In our developer environment, we have the following packages installed.
Dataverse Base Portal 9.3.2307.91
Power Pages Core 1.0.2310.50
In our client environment, since it's created recently, the versions are different
Dataverse Base Portal 9.3.2307.94
Power Pages Core 1.0.2310.71
