How to Resolve The “Out Of Date Nintex Forms” Error In SharePoint Online

I have customized my SharePoint Online custom list add Form, using Nintex Forms for Office 365. It worked perfectly. Subsequently, I thought of adding some validations, using JavaScript code. Hence, I followed the steps given below.

Step 1

Click on Form Setting on Nintex Form designer screen.

Step 2

Under Custom JavaScript option, I simply wrote alert (‘Hello’).

Step 3

Subsequently, I published the form.

Step 4

Now, when I try to add a new item in my custom list,  it opens Nintex Form and I get the error given below.

Once I clicked on OK, the list form closed and default list view was displayed.

Hence, I thought that maybe my Nintex Form for Office 365 app was outdated. I searched how to update Nintex Forms for Office 365 app. I found so many links but I found that my Nintex Form is up to date.

Thus, it gave me trouble. I kept on searching. Finally, I found the solution. When I found the solution, I was really disappointed with Nintex Forms error message, as it is misleading.

The problem was with my JavaScript code and not with the app.

What did I do wrong? I wrote the wrong syntax.


Instead, write the code given below. 


The only mistake was I missed the semicolon (;) and I got this error message. I corrected the code and everything was fine and I got an alert message with “Hello”.

Thus, I thought of sharing this, because the error message is somehow misleading in finding the solution.

Thus, when you get the error like this, then do the checks given below.

  • If you have injected any kind of JavaScript code to Nintex Forms, then please make sure that the code has proper syntax. 
  • If you don’t have any JavaScript code, go for updating Nintex Forms for Office 365 app.
  • It saved my time to a phenomenal extent. I hope, this will save time for others also.
  • If you have any query regarding this or you need more information, please feel free to ask in the comment section.

Any question or feedback or suggestion, please do comment and let me know.
