While running the insert without validation it works, but when I added validation like targetdate must be future date and trying to show in form twoway binding, then this error started.
No idea on which direction I need to think of.
Error:

Tried to debug the code and the error is triggered only when validation added + towway binding added. Without validation+ two way binding tags, everything works fine.
