Hi all,
I’ve got this strange type cast error for the jdbc persistence. It’s succesfully creating tables and writing data into the tables. In the attached debug log you can see the data gets read from the database as well (timestamp: 2021-09-22 20:50:36.233). But then there is a class java.lang.String cannot be cast to class java.lang.Integer error.
I’m on Openhab 3.1.0. Any advice will be greatly appreciated.
Here’s the debug log:
