SQL trigger item contains null values after conversion to isolated model

[skrizan7]

I am trying to convert an Azure function from .Net6.0 and In-process to .Net8.0 Isolated model.

The function uses Azure SQL triggers for an Azure SQL server database with change tracking enabled. When the triggers fire updates are made to a container in a Cosmos DB.

This is working fine using .net 6.0 and in-process model of the function. The trigger fires with the following code in a c# .net8.0 function using isolated model, but the item contains null values for all of the fields. The same model and dbcontext are being used in both the in-process and isolated versions, for the example provided.

I have googled and tried AI platforms for solutions but have not found any help.
