Find objects API do not work properly for index patterns

[al-ah]

Kibana version:
7.12.0

Describe the bug:
I need to get the index patterns title and fields. Its worked correctly in kibana 7.10 but now if i create new index pattern then get index patterns i have no fields in result.

Steps to reproduce:

1. post new index :

POST test-1/_doc
{
  "name": "foo",
  "family": "bar"
}

2. create new index pattern in kibana
   

3. use find objects api

/api/saved_objects/_find?type=index-pattern&search=test-*

4. result in kibana 7.10
   

5. result in kibana 7.12
   

Expected behavior:
With the implementation of Find objects API, it is also necessary to obtain the fields based on the index pattern and bring them in the fields section.

thanks

Hi @alah64

Looks like we no longer fetch fields via /api/saved_objects/_find since #83891 (released in 7.12)

Get field mapping API

@elastic/kibana-app-services could you confirm?

@alah64 You'll get what you need by using the Index Patterns API - #83576 - using other methods (such as the field mapping API) may produce inconsistent results.

Thank you for your answer.
Because I do not know the names of the fields and I need all the fields at once, Get field mapping API is not applicable.
I will test the Index Patterns API, the only problem is that this method does not exist in versions 7.10 and earlier. I have to find a solution to detect the version in Kibana plugin and go one of the two methods based on it .

The field caps api might be more appropriate - https://www.elastic.co/guide/en/elasticsearch/reference/current/search-field-caps.html

It depends upon if you want the fields from indices or if you want the fields from an index pattern.

If you're writing a plugin, then you can use the data plugin to access index pattern functionality instead of the index pattern REST API.

Closing issue as several months have passed. Feel free to reopen if needed.

This problem does not exist in version 7.16.2 , also can use index patterns api since version 7.12
