from https://github.com/elastic/kibana/issues/167992

the error `_id must be unset or set to [GvMPW29fWPE5Sr2ZAAABivq9G6A] but was [_id] because [.ds-metrics-logstash.monitoring-default-2023.10.04-000001] is in time_series mode`

No `_id` field is sent as part of the request so the error must be internal to the endpoint functionality.

This is preventing the creation of runtime fields against TSDS data views in kibana.

Steps to reproduce via kibana - 
1. Install `Kibana Sample Data Logs (TSDB)` sample data
2. run via dev tools console
