Error on Users Page (and API)

[jason]

Hi there,

When I navigate to the user tab of my cloud hosted FA instance (https://[myapp].fusionauth.io/admin/user/), I see the following error message: "FusionAuth encountered an unexpected error. Please review the troubleshooting guide for assistance and the available support channels. https://fusionauth.io/docs/v1/tech/troubleshooting/"

In the server logs I am able to see the following error:

All shards failed for phase: [query]
org.elasticsearch.ElasticsearchException$1: Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [login] in order to load field data by uninverting the inverted index. Note that this can use significant memory.

Is there some way to fix this?

@jason Try going to System -> Reindex and re-indexing your users. I received the same error and this resolved it for us. Everything was working on Friday for us, so it looks like something broke over the weekend.
