Oh, I just realized that the error also occurs when the validation is off, because also here, Integer/Float expects a value that cannot be empty.

So, you need to change the datatype in your BO from Integer/Float to String and add a validation before executing the BO (as described in 1b)) or work with default values for Integers/Floats (as described in 2)).
