copy action allows you to copy the value of a field from one field to another. It takes two arguments:
from, which specifies the source field, and
to, which specifies the target field.
Here’s an example of how you might use the
copy action in a YAML file:
actions: merge_filter: action: copy from: filters to: attribute_filters_filter
In this example, the
copy action will copy the value of the
filters field to the
attribute_filters_filter field. If the
filters field is empty or does not exist, the
attribute_filters_filter field will also be empty or will not be created.
