 #### EUI component is missing types
 
-1. Check https://github.com/elastic/eui/issues/256 to see if they know it’s missing, if it’s not on there, add it.
-2. Temporarily get around the issue by adding the missing type in the `typings/@elastic/eui/index.d.ts` file. Bonus points if you write a PR yourself to the EUI repo to add the types, but having them available back in OpenSearch Dashboards will take some time, as a new EUI release will need to be generated, then that new release pointed to in OpenSearch Dashboards.  Best, to make forward progress, to do a temporary workaround.

 In this example, if the `.opensearch_dashboards_4` index existed prior to OpenSearch Dashboards booting, the entire migration process will fail, as all OpenSearch Dashboards instances will assume another instance is migrating to the `.opensearch_dashboards_4` index. This problem is only fixable by deleting the `.opensearch_dashboards_4` index.
