Hi @mulki ,
This is very strange, if re-creating the connection and re-creating the Flow cannot solve the problem, you can directly refer to the properties contained in the trigger body through expression.
The basic composition of Expression is triggerBody()?['PropertyName'].
For example, if you want to get a Title, you can refer to the configuration below.

Or you want to get Created by email, the expression should be triggerBody()?['Author']?['Email']. Property can be obtained from the trigger body.
Best Regards,
