@dinesh11515 while we wait for the frontend team reply, could you make sure the checks are green?

@jmg-duarte fixed lint issue, can we run checks again

Hi!
Yes, we will need to handle the validation error on the frontend side, as @dinesh11515 said, but it can be done after this PR is merged.
My only concern is that we could have DCA orders, where buyAmount is supposed to be zero by design. In that case this change will prevent creation of such orders.
