Azure Logic Apps with Form Recognizer - Get Array definition in optional settings entry

I created an Azure Logic App using Form Recognizer to analyze PDF based invoice files. I actually recognized that the process is working well, but in encountering issues in enabling the barcode option. I always receive "Enter a valid array" when i put this option into the form.

Does anyone know what value i have to insert in that field?

Thanks folks!

I already tried to add the following into the field:

• ["Barcodes"]

• Expression: items('For_each')?['fields']?['Barcodes']?['value']

• Expression: items('For_each')?['fields']?['Barcodes']

None of the above worked. Returned always NULL/Empty

To solve the issue use below design:

In Standard Plan:

In compose give value barcodes.

Then:

Output:

In Consumption Plan:

You can directly use the value as below:
