When defining app settings prior to execution, you are now able to set null or empty values for the available inputs. This is possible using the two new buttons placed next to the inputs under the Define App Settings tab.
The Set null option is available both for simple inputs (such as strings or numeric values) and complex ones (such as arrays, records or maps).
Set empty is available as a button only for complex inputs (arrays, records and maps). For most of the simple app parameters, such as strings, empty value is set by simply removing the value from the input field and leaving the field blank.
We have also introduced support for displaying certain more complex input types, such as arrays of records, that are now also available through the visual interface.
