Js error if table not found

Problem/Motivation

Console js error.

Steps to reproduce

Install Inline Entity Form

Create a node type that has a multi-value plain text field and some nodes.

Create another new node type that has a multi-value entity reference field, pointing at the first node type. Set the form widget to use the "IEF - Complex" option. This provides the ability to edit referenced nodes while editing the parent.

Create a new node of the second type and add some first node type nodes to the field and save the node.

Edit the node (type 2), and then click to edit one of the referenced (type 1) nodes.

The error is happening for me on these nested tables. The code runs but they're not showing yet so are not found.

Proposed resolution

If the table doesn't exist, don't change properties or do stuff.
