Error with Structure Listing entries

Question

EE: 2.7.1
Structure: 3.3.12

Here's what I'm doing when I get the error below:

1. Created a Template group listings and a template in that group called contacts.

2. Created a channel contacts with a few fields.

3. Went to Structure CP

   • Channel: Contacts
   • Type: Listing
   • Options: listings/contacts

4. Went to EE CP to create a new entry in the contacts channel.

5. Entered data into fields, then in the 'Structure' tab, I selected:

   • Structure Page URL: [autofilled from field entries]

   • Structure Template: listings/contacts

   • Listing Channel: [selected Contacts]

And we're getting this error:
