The process hangs when trying to export a particular form’s submissions

When trying to export, for example, the last two submissions ( https://c2n.me/4jQFVKg.png ), the export occurs, but the resulting file contains only the field names, not the content of the submissions ( https://c2n.me/4jQFZnh.png ).

After I enabled ‘legacy mode’ to display submissions and tried to export a single submission from the list using the context menu command ( https://c2n.me/4jQGnuz.png ), the site displayed a WordPress error.
Here is the text of the error notification email:

Ошибка с типом E_ERROR возникла на строке 608 файла /var/www/хххххх/wp-content/plugins/ninja-forms/includes/Helper.php. Сообщение об ошибке: Uncaught TypeError: Return value of WPN_Helper::maybe_escape_csv_column() must be of the type string, array returned in /var/www/хххххх/wp-content/plugins/ninja-forms/includes/Helper.php:608

Hello,

I understand you’re facing some challenges with exporting your Ninja Forms submissions, and I’m here to help.

First, let’s address the batch export issue. It seems that for this particular form with a large number of fields, the export process is hanging. This can be very frustrating when it happens.

For the Excel Export, set the file type to XLS instead of XLSX. For large files, XLS often ends up working out better.

Next, the problem of exported files containing only field names without submission content is certainly unexpected. We want to ensure that your submissions are correctly exported.

Double-check the submission action within the form and make sure it has been enabled. Often this is why that type of result is happening. For more information see, https://ninjaforms.com/docs/submission-management/

Lastly, the error you encountered while exporting a single submission is concerning, and we want to get to the bottom of it.

To get this issue sorted out effectively, I recommend reaching out directly to our Customer Success team through our contact page. They’re well-equipped to dive into these challenges and provide you with the best solutions.

We appreciate your patience and understanding as we resolve these export issues. Please don’t hesitate to contact our team, and we’ll assist you every step of the way.

Hello,
thank you for your answer.

I followed all the preliminary steps recommended by your support team before requesting help. On the same day that I posted this post, I created a test version of the site, submitted a support request via the contact form on your site, and sent my site access details.

I can assume that the attached protocol of the errors that occurs when trying to export the list of applications simplifies the problem considerably.

As you probably understand, the inability to export form submissions is a serious problem and needs to be addressed as quickly as possible. I hope for your understanding.

As of this moment, I have not received any response from the support. I am looking forward to it.

Hi Alex

The ticket was escalated yesterday and the Engineers are looking at it.

Thanks

Hi Alex

I wanted to circle back here and update users in case someone else runs up on the same issue and finds this post in a search.

The problem was related to one of the textboxes in the form sending in data that wasn’t expected. Specifically, the textbox was supposed to send a string, but it sent an array instead. We created a patched version and Alex confirmed this fixed the issue with submissions. The fix is merged into the plugin and will be added into an upcoming release.

Thanks!
Mia
