Kibana 7.17.1 -- can't find index pattern uuids?

[Russell_Fulton]

On several occasions with older release I have exported saved objects fiddled with the pattern uuid and then imported them back.

I am now doing a major migration of dashboards where I need to change the index patterns,

firstly I note that the older visualisations and dashboards have different representations to more recent ones which don't have long random ids in the reference sections.

secondly when I export the index pattern that I recently created and wish to change the dashboards to use it doesn't have uuid either

    "fieldAttrs": "{\"event_source\":{\"count\":13},\"event_class\":{\"count\":4},\"assoc_ip\":{\"count\":3},\"src_ip\":{\"count\":1},\"detail\":{\"count\":3},\"event_type\":{\"count\":2},\"service\":{\"count\":1},\"status\":{\"count\":5},\"user_name\":{\"count\":124},\"user\":{\"count\":2},\"data\":{\"count\":1}}",

}

  "excludedObjects": [],
  "excludedObjectsCount": 0,

}

Lastly, at some point in my researching this issue I found reference to using the Kibana api to get full details of index patterns. I regularly use the ES api but have never used the kibana one. I can't figure out which user I should authenticate as. Should I set up a user for this and if so what roles should I give it.

I figured out which account to use to get into kibana api (elastic works).

when I try to use the GET <kibana host>:<port>/api/index_patterns/index_pattern/<id> to retrieve an object I always get "not found". I could not find a method of retrieving all index patterns (giving an <id> of '*' also retuned not found.

what is the api expecting as an <id>?

The patterns are all defined in the default space.
