Use an array aggregator to map into the Values field (Turn on the “Map” toggle)
Every result (item/record) from a search/match module will output a bundle. To “combine” them into a single structure, you’ll need to use an aggregator of some sort.
Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and has applies to many use-cases.

The Array Aggregator module allows you to build a complex array of collections for a later module’s field to map multiple items (collections) to it.
Here is an example of using the “Target structure type” of an Array Aggregator module:
As you can see, the “Map” toggle on fields are used when you have an array. You can easily build an array variable to map to a field, by using an Array Aggregator module and select the “Target Structure Type” as the future field you want to map the array into.
You can use the built-in function ifempty with emptystring
e.g.:
{{ ifempty(variable; emptystring) }}

Ive come across this error. Un-map (turn off mapping) that field so it is NOT updated. Now, add a New Update Wordpress Post module, this will only update 1 thing, can you guess? Now connect it to the original one but with a Filter that blocks the flow IF that variable IS Empty. HTH.
