Our site uses the Paragraphs module, which is similar to Field Collections. I created a Paragraph Type with an EntityReference field in it. Set the entityreference to autocomplete and then enabled the Add and Search options.

When I try to create a new paragraph with this type, I get this error:

An AJAX HTTP request terminated abnormally.
Debugging information follows.
Path: /system/ajax
StatusText: n/a
ResponseText:
My Demo Site
Error
The website encountered an unexpected error. Please try again later.

ReadyState: undefined

And then when I just try to edit the entity reference field on the Manage Fields page, I just get some unknown error page (even though I have all error reporting enabled, and nothing in syslog). Seems related to the "Add" option. If I delete this field and just use the Search option then I don't get the error (although it also doesn't actually show the Search button when using the entity reference field).

In fact, it doesn't have anything to do with the Paragraphs module. Just enabling the Add button on a normal content type entity reference field causes the error. Since I cannot see the actual error in any logs, I will try some of the recent patches here in the issue queue to see if one of them fixes this.

OK, the patch in #2380041: Unsupported operand types error after upgrade to 7.34 fixed this. That really needs to get committed asap!!
