File Upload hangs when submitting

Hi ​@kirkie4567,

This is a tough one to diagnose on this platform. The question may be more suited for Nintex Support.
When you say the form hangs, do you see a submission screen with a spinner, but no progression from that point?
Do you see any errors in the browser console (F12)?
Can you submit items to that list with attachments using the default SharePoint form?
Is this list the only one with the issue, or do other lists in the site/site collection have the same issue?

Hi ​@SimonMuntz 

Thanks for replying.

• I do see the submission screen, but no progression from that point
• I do not see any issues
• I am not sure how to submit using the default Sharepoint form
• As far as I can see, this is the only list with this error

Regards

Kirk

To test with the default SharePoint form, you first need to export the Nintex form to back it up.
Then, delete the Nintex form from the Nintex form designer.
Now, create a new item on the list, and the SharePoint form will open instead of the Nintex Form.
When you add an attachment to the default SharePoint form, does the attachment submit?

The purpose of the test is to determine whether the issue originates from Nintex or SharePoint.  This test eliminates Nintex from the equation.

To restore the Nintex Form, open the Nintex Form designer and import the form file you exported.

You said you tried a .txt file. Have you tested with any other file extension?

​@SimonMuntz When I delete the Nintex form, the SharePoint form does not have the File Upload control in it. I couldn't get the form to show the control. Seems like it is a Nintex problem. I have another form with the identical control, but the form submits no problem

Thanks ​@SimonMuntz  there is something wrong with the list. I successfully created a new list and imported the settings and form into it, and it works perfectly.
