Filter value N/A in the URL not working

Hello All,

On if my filters has value "N/A" and I want to pass it in the URL when a dashboard is opened. We are also using JS API to embed dashboards and our Tableau Server Version is 2019.3.1

I have tried many things but the filter does not load with N/A applied. I have checked the tableau kb article https://kb.tableau.com/articles/issue/special-characters-in-url-parameters  and tried but it does not work.

Passing N/A in the url

%26Operator%3DWolverine%26State%3DUtah%26First%5c%20Production%5c%20Year%3DN%5C%2FA
&Operator=Wolverine&State=Utah&First%5c%20Production%5c%20Year=N%5C%2FA
&Operator=Wolverine&State=Utah&First+Production+Year=N%5C%2FA
&Operator=Wolverine&State=Utah&First+Production+Year=N%2FA

I have also tried to pass the value in JS like below

      tableauViz = new tableau.Viz(frameDiv[0], url, {
        highdpi: true,
        hideTabs: true,
        hideToolbar: true,
        "Operator": "Wolverine",
        "First Production Year": "N/A",
      });

But none of the above work, has anyone encountered such issue? Any help in this would be greatly appreciated.
