Fields error in redis dashboard

Hi everyone,

I as trying to get the data though Kibana dashboard [Metricbeat Redis] Overview ECS but I'm getting the following error:

[esaggs] > "field" is a required parameter

When I edit the charts with empty data I see an error in the split series part, where Kibana is not finding the field it was supposed to be based on:

Maybe my index doesn't have this field, but I don't know how to check which field Kibana looking for.

Kibana seems to be looking for the redis.keyspace.keys field, you can check in discover by expanding a document to see if that is present in your index.
