field(namespace: Namespace | Null = null, name: String): PathElement

This function creates a PathElement data type to use for selecting an object field and populates the type’s selector field with the given string.

Some versions of the update and mask functions accept a PathElement as an argument.

Introduced in DataWeave version 2.2.2.
