Hey "@abc 123", it's not a Required proble.
The action to add an Opportunity to the table have the filed "Contact" (a relationship to other table), so I have to put the ODATA there. But if I create a "generic" action to create the Opportunity and put an ODATA that I get in a previous action, the action will fail if the ODATA is empty.
That's why I created a switch asking if the Get Contact is empty and created two actions for Add Opportunity, one with the Contact and another without the Contact.
But this is not nice because I use a lot of fields when creating an Opportunity so doing everything twice is a burden.
That's why I'm asking if there's a better way to create an Opportunity with/without the Contact.
