There's a bug in the component when you set a value for Redis without the ExpiresAt property. It sets the expiry date to a negative value.
Line 128 at RedisConnector.cs should be changed to "else if (ssExpiresAt > new DateTime(1900,1,1))".
This will be fixed soon,
Thanks for the heads up!
A new release was done for OutSystems 11 with the bug fixed.
Thanks
