The input is empty.

Getting issue "The input is empty." when clicking on augmentor field types on node form

Steps to Reproduce

• Add augmentor type Suggest Body Summary
• Add Suggest Body Summary field type
• Add content and click on Suggest Summary.

Proposed solution

Replace

 const hasSourceFields = sourceFields.length > 0;

with

const hasSourceFields = Object.keys(sourceFields).length > 0;

in augmentor_library.js file as sourceFields variable contains object and not array
