Workaround for 'Too Many Requests' Error in Jira Cloud Dashboards

Background

When users has multiple gadgets on a dashboard, multiple reloads are required for the gadgets to display properly.
The console logs shows that a large amounts of request results in 429 (Too Many Requests)

Root Cause

There is a known issue for Jira Cloud where the REST API calls can only call 100 requests each time.

If there are many gadgets on the dashboard page, it may cause the browser to make a lot of requests (for CSS and Javascript files).
Some browsers like Chrome has a limit on the number of requests per page, so it will result in the "429 (Too Many Requests)" error.

You may verify the number of requests going to the Network tab in the Developer Tools.

Possible Workaround 

• Reload the dashboard again so that it can reuse the cached resources

• Reduce or consolidate the number of gadgets on the dashboard (We recommend not exceeding 8 gadgets)

• Refine the JQL filter to reduce the scope of issues retrieved
