mapValues returns null when adding certain condition
I'm using the following expression to parse date fields in an object. It works correctly. However, when I replace key.contains('date') with another string to compare, the expression returns null for ...
Thank you. This was pretty close to the problem. If there is an error in a function called in mapValues, a null object is returned as the result of map values.
