Error on UPTIME

ror: [illegal_argument_exception] Fielddata is disabled on text fields by default. Set fielddata=true on [] 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.

any idea on this please?

This is due to deleting data in Elasticsearch while heartbeat is still running. The easiest fix here is to:

  1. Stop heartbeat
  2. Delete your ES heartbeat indices: heartbeat-* should match them
  3. Start heartbeat

Thanks for this, it worked:)
