2. Go to Index management and click on the created index
3. Click on the Mappings tab. It shows an error:

Error in console:

Uncaught TypeError: Cannot read properties of undefined (reading 'label')

This error seems to come from this line:

kibana/x-pack/plugins/index_management/public/application/components/mappings_editor/use_state_listener.tsx

Line 59 in 1c3705b

label: TYPE_DEFINITION[dataType].label,

It probably fails because of an unsupported data type. I looked through the mappings and noticed one mapping with type counted_keyword which is not in the supported ones:

"profiler_stack_trace_ids": {
    "type": "counted_keyword"
},

To see if this is the cause, I created a new index with the same mappings but removed this specific one. Then verified that the Mappings details page loads and works as expected.

According to elastic/elasticsearch#101826, this new type is considered experimental and therefore not publicly documented. We should probably wait until documentation is available before supporting it in Kibana. cc: @alisonelizabeth

Edit: We could still resolve this bug by better handling unsupported types.

Let's discuss this. In this case, the mappings editor is being used to view index mappings in which case I think we would want to support it. However, I agree, that we may want to wait before adding the ability to add this mapping type via the index/component template UIs.

Yes, that makes sense to me! We can still display the unrecognized type in the editor:

In fact, an unrecognized type can also be added through the UI, using the "Other" type option.
