Expression to set menu input in flow element as "untouched" ..?

Hi, I try to use Adobe Sign connector and what I need is variable number of signers in my flow.

To specify the signer you need to add three data elements for each signer: e-mail address (string), signing order (int) and choose his role from the menu.

Adobe Sign API allows dynamic number of signers, but if you even specify the name of one of above mentioned data elements (you pass en empty e-mail for signer_5 for example) then the API throws an error (incomplete data).

So as I understand the need is to create such an expression which returns something which is treated as if this form element was empty (without any expression).

What to return?

Re: Expression to set menu input in flow element as "untouched" ..?

I'd add additional info:

If I set e-mail to string expression:
if(empty(body('Pobierz_element')?['RepOp_2']),null,body('Pobierz_element')?['RepOp_2'])
or
if(empty(body('Pobierz_element')?['RepOp_2']),'',body('Pobierz_element')?['RepOp_2'])
I get this in the request

If I change the type of the variable used in this field to "Object" and use the expression:
if(empty(body('Pobierz_element')?['RepOp_2']),null,body('Pobierz_element')?['RepOp_2'])
I cannot see the field in the request (so it seems to the some trick), but the API request fails anyway with:

What else can I try ..?
