I'm using Kibana's (5.4.0) and while trying to access _Dashboard_ for 30 days, I'm getting following (red) error:

```

yet with 7 days, I'm getting (yellow) error:

Please advise.  
Thanks in advance!

What does ES show in the logs at this time?

```auto
Caused by: java.lang.IllegalArgumentException: Fielddata is disabled on text fields by default. Set fielddata=true on [shopId] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.

```

You need to update your mappings as the error suggests 🙂

per my mapping _shopId_ already set as _keyword_ type:

> ```
> "shopId": {
> "type": "keyword"

</div>

after I \__reindex_ all of my indices, previous error that was appearing in logs before went away, however

> Visualize: Request Timeout after 30000ms

still showing up on top of screen, and I'm not seeing anything in logs when I get an error...
