How can I pass an empty string( "") as a parameter?

I need to make a PUT request to an API where updating a value to empty requires using an empty string (""). If the value is null, the field is ignored, and the value is not updated.
The problem is that the returned value is null when I try to use an empty string in Zapier, whether through Code or Formatter. Is there a way to resolve this?
 

{

    value: “”, //accepted
    value1: null, //not accepted

}
