Can I fix the "bool (false)" Duplicate Submissions Terminator error?

Every time I try to add Duplicate submissions Terminal to a Form, the attached page loads.

Can you let me know if there is a fix?

I'm not sure I understood your question "Every time I try to add Duplicate submissions Terminal to a Form". Are you referring to adding the form to the duplicate submission site?

I tried adding a form to the http://duplicate-delete.jotform.io/,and I was successful.

May we know the form ID you used in the duplicate-delete app?

We will wait for your response.

I am not able to add a form, let me show you my process in screenshots.

1: This is what I see on http://duplicate-delete.jotform.io/

2: I click "Login with JotForm!"

3: I click "Allow", and the page only says "bool (False)"

Can you help me?

Have you tried using other web browsers? Firefox? Most probably its your antivirus that is stopping oauth.jotform.com from connecting that is why it is giving you a bool(false)

Kindly check your antivirus and allow oauth.jotform.com and try to use other web browsers.

Let us know how it goes.
