Forward engineered generated column inserts error 3105

[James Strong]

Hi I'm trying to use MySQL Workbench .23 to insert a row into a table that has a generated column but keep getting an error about the value entered is not allowed.

I've tried null, \func, DEFAULT and even empty string and the SQL script instead of leaving that field out puts a value in the field.

How do I get Workbench to stop generating a value for that virtual field and or what value should I put since null doesn't work.

It is a virtual column and not a stored one.

Thanks
