Power Automate FIlter Array with Array Object as Attribute

Question

i have a Object-Array1 with some Attributes that are Object-Array2. I want to filter my Object-Array1 only to these elements, that contain a special value in Object-Array2. How wo i do this? Example:

{
  "value": [
    {
      "title": "aaa",
      "ID": 1,
      "Responsible": [
        {
          "EMail": "[email protected]",
          "Id": 1756,
        },
        {
          "EMail: "[email protected]",
          "Id": 289,
        }
      ]
    },
    
    {
      "title": "bbbb",
      "ID": 2,
      "Responsible": [
        {
          "EMail": "[email protected]",
          "Id": 1756,
        }
      ]
    }
]
}

I want to filter my Object-Array1 (with title & id) only to these elements, that contain [email protected]

How do i do this in Power Automate with the "Filter Array" Object? I tried this way, but didn't work:

Answer 1

Firstly, you haven't entered an expression, you've entered text. That will never work.

Secondly, even if you did set that as an expression, I don't think you'll be able to make it work over an array, at least, not without specifying more properties and making it a little more complex.

I think the easiest way is to use a contains statement after turning the item into a string ...

The expression I am using on the left hand side is ...

string(item()?['Responsible'])

... and this is the result ...
