Why am I getting the following error when I try to upgrade my site from Drupal 7 to 8 using the Migrate Upgrade module? After a progress of 11% my site's throwing an Ajax error:

An AJAX HTTP request terminated abnormally.

Debugging information follows.

Path: /mysite/?q=en/file/ajax/field_slideshow_image/und/form-ESe-qn-oh9D4OVpLClBz2wTv1mHUxaTWHmj2hi5V3aw

StatusText: n/a

ResponseText: The page cannot be displayed because an internal server error has occurred.

ReadyState: undefined

The actual error message is the following:

Source ID comment_node_industry_recognition: Attempt to create a bundle with an ID longer than 32 characters: comment_node_industry_recognition(). (/media/public_html/public_html/drupal/drupalmigrationfinal/‌​core/lib/Drupal/Core‌​/Entity/Entity.php:4‌​08)
