The DateTimeConverter format y%#### does not work the way I understand it should. Please help.

I am sending this date, Oct-23, through the DateTimeConverter. I have set t he input format as %b-%y2099. The DateTimeConverter is failing to parse the date with the message "Attribute(string: UTF-8)         : `fme_expression_warnings{0}.message' has value `Failed to evaluate expression '@DateTimeParse(Oct-23,%b-%y2099,repair)'. Result is set to null'".

What am I doing wrong?

I have attached a sample project that demonstrates the failure.

My FME Form version is FME(R) 2023.1.1.0 (20230928 - Build 23631 - WIN64).
