I deleted and recreated an Index Pattern which broken visualizations associated to the old Index Pattern.
I used the following GET request on Dev Tools Console to list our Index Patterns and obtain the new Index Pattern's UUID, but could not find the pattern.
I also search in
Ultimately, the easiest way to find the UUID of the new Index Pattern was from the link itself under Management > Kibana > Index Patterns
Right-click the Index Pattern and copy link, then paste into text field and note the UUID at the end of the URL.
