you forgot to ask a question that can be answered / solved.

The error can be explained by the source code of the isVflex method on grid itself (however that information might not help your actual problem, whatever that might be)

v8.5.0: https://github.com/zkoss/zk/blob/v8.5.0/zul/src/org/zkoss/zul/Grid.java#L399-L408

v9.0.1.2: https://github.com/zkoss/zk/blob/v9.0.1.2/zul/src/org/zkoss/zul/Grid.java#L412-L421

The value 'auto' is not handled by this method, leading to this error.

If you provide a correct value (null, '', 'true', 'min' or a number) the error will go away.

The same exception should have happened in both versions 8.5.0 and 9.0.1.2 given the value 'auto'.

Unfortunately you didn't provide a working/failing example to investigate so I can't comment on that.

Window execution create components zk version 9.0.1.2
