What is your goal?

Feature image upload that is generated via GPT in Wordpress via automated bloging

What is the problem & what have you tried?

In my Wordpress blog automation i want the Featured image to be set but this setup up is giving error.

Error messages or input/output bundles

BundleValidationError
Validation failed for 1 parameter(s).
Invalid number in parameter ‘featuredMedia’.

Origin
Make

Automatic error handler
If you want to handle this error automatically, choose one of the following options. This will create a new error-handler route in your scenario. You can then expand the route in any way you like.

Welcome to the Make community!

The field accepts a single image, which has to be uploaded using the Wordpress “Create a media item” module first.

If you want to upload all the images, see below.

From your screenshot / output bundle, it appears that you have an array of items. What do you do when you have an array?

“Looping” Through Array Items

When you see an array in a module’s output, think of using an Iterator module. This allows you to individually access and process each item in the array.

In this example, this variable is an array of items (collections). You’ll want to map this variable in an Iterator module.

Question: Have you tried mapping your array variable into an Iterator module, ran the scenario once, and view the output? Then …

Combining Bundles Using Aggregators

Every result/item from some module types (like Trigger / Iterator / List / Search / Match modules) can potentially and likely output more than one bundle. These multiple bundles will individually run subsequent modules once per bundle, which is not optimal in most cases:

• one operation per bundle per module, which could lead to…
• use of multiple credits per bundle per module (some modules use more than one credit)

Aggregator Example

The “Search Rows” module runs one time, returning 999 results (999 bundles).

• Without Aggregator: the tools module run 999 times (999 operations)
  

  
  
  (and if there are more modules, they run 999 times each)

• With Aggregator: the tools module only runs 1 time (1 operation)
  

  

	Warning:
	This can easily use your entire quota of credits if you are not careful or fail to understand this concept.

To “combine” multiple bundles into a single variable, so that you can process all of the items in a single operation, you’ll need to use an aggregator. Aggregators is a type of module that accumulates bundles and outputs one bundle (unless you are using “Group By”). An example of a commonly-used aggregator module is the Array aggregator module.

You can find out more about some other aggregator modules here:

• Array aggregator
• Numeric, Table, Text aggregators
• JSON aggregator
• CSV aggregator
• Archive (.zip) aggregator
• other app-specific aggregators

Question: Which is the best aggregator do you think you’ll need for your use-case?

Mapping a Complex (Collection) Structure Into an Array Field

The Array Aggregator module is very powerful because it allows you to build a new complex array of collections that matches a later module’s array field to map multiple items (collections) to it. Such fields initially may allow you to manually add individual items, but toggle the “Map” switch on, and you can map an array variable (from an Array Aggregator) containing multiple collections.

Simply select the respective “Target structure type” in an Array Aggregator module.

As you can see from the above example, the “Map” toggle on complex fields are used when you have an array variable (like from an array aggregator).

	Note:
	Other combinations of modules may also allow you to generate an array that matches a future module field’s array structure, like “Aggregate to JSON + Parse JSON”, or “Create JSON + Parse JSON”, but this is an advanced topic.

Question: Are you mapping your array into a field that accepts more than one item/collection?

Example

Here is an example of how your scenario could look like:


^{This is just an example. Your solution may or may not look like this depending on requirements and actual data.}

For more information, see “Mapping with arrays” in the Help Centre. I also suggest going through the Make Academy, which also covers the use of Iterators & Aggregators.

I’d recommend going through the Make Academy if you haven’t yet!
