I set up private file directory at /var/www/private to keep upload files from webform and setup permission on directory and files (664 for files, 775 for directories). When I click on upload button and select file, it throw an exception -
"An unrecoverable error occurred. The uploaded file likely exceeded the maximum file size (32 MB) that this server supports." However, file size is few kilobytes which is less than 1 MB but exception shows exceeded the maximum file size.

Note: Solution is running on Drupal 8.3 on VM (Vagrant)

An unrecoverable error occurred. The uploaded file likely exceeded the maximum file size (32 MB) that this server supports.

Is a generic error that assumes the updated file exceeded the maximum file size but it could be permission or access rule or even a theme issue.

@see \Drupal\Core\Form\EventSubscriber\FormAjaxSubscriber::onException

Other people are having this issue.

@see #2658718: Custom form AJAX error of upload file size shown even with no file field.

  • As a test, have you tried uploading files using the public file system?
  • Are you using a custom theme? Have you tested the issue using the Bartik theme?
  • Can you replicate the issue using a plain vanilla D8 instance?

Thanks for sharing link. I found a cause which has not define early on template (twig) file :
{{ element.form_token }}
{{ element.form_build_id }}
{{ element.form_id }}
{{ element.actions }}
After define it allows browse file from local directory. However, error message is misleading.
