Testing valid shape

I have a script that is doing layer booleans, modifiy, deleting shapes. I need a way to test if the variable has a valid shape. I am getting the message in the ciw dbGetq: object is a purged/freed object - db:0x2ab1132fa2.

I know the shape it is specifying has been deleted.

Is there clean way of testing if a shape/variable is valid in a boolean statement or a script that returns a boolean?

Thanks

I have tried some various uses of getWarn, errset, ~>isShape, symeval, and maybe some others.

Have you tried this?

dbIsId( 
d_id 
) 
=> t / nil
 
Returns t if the argument is a valid database object ID, otherwise,
it returns nil.

Nope, I did not and it returns the value I want

Big thanks
