Issue Summary

Using the AWS Import module for Assets, trying to create the Predefined configuration the UI never appear to finish (the rotating animation keeps on going forever).

This is reproducible on Data Center: yes

Steps to Reproduce

1. Install the Assets - AWS Integration
2. Enter the AWS module-specific configurations
3. Click on the Create predefined Structure and wait for the green tick
4. Then click on the Create predefined configuration

Expected Results

Predefined configuration gets created and the UI shows another green tick mark

Actual Results

• The rotating animation (implying working-on-it) keeps on rotating forever (reproducible in-house)
• and in some cases might report a Gateway timeout on the UI as a popup error (not reproducible in-house)
  

Workaround

Refreshing the page after a while (depending on the depth of the configuration) the predefined configuration does get created in the background without any issues.
