Greetings!

I am trying to port the elastic-kibana-postfix .json files to .ndjson files to visualize a dashboard for Postfix for Elasticsearch 8.10.2. The PR and issue discussion are available at the following links:

> <https://github.com/ActionScripted/elastic-kibana-postfix/issues/15>
>
> Is there a latest version of the dashboard JSON files in .ndjson format that is …required for ELK 8.x?

> <https://github.com/ActionScripted/elastic-kibana-postfix/pull/16>
>
> The .json files have been ported to ndjson files and they get imported cleanly. …The same has been tested on Elasticsearch v8.10.2.

The .ndjson files get imported correctly, but, when I try to open Dashboards -\> [Filebeat Postfix] Overview it throws the following error:

`Cannot read properties of undefined (reading 'searchSourceJSON')`

I removed the searchSourceJSON field from kibanaSavedObjectMeta key. Is this mandatory? Can anyone please assist in porting the JSON files correctly?

Thank you!

How are you generating those `ndjson` files?

I am not generating the ndjson files. I manually converted the json files from [https://github.com/ActionScripted/elastic-kibana-postfix/tree/master/kibana](https://github.com/ActionScripted/elastic-kibana-postfix/tree/master/kibana) to ndjson until they imported cleanly.

Thanks for your reply!

Wouldn't be a better approach to import those saved objects in a clean kibana instance, upgrade the stack up to the desired target so Kibana migrates them appropriately, and then finally export them? 🤔

I have been able to import the .json files to 6.5.1 Elasticsearch and Kibana versions. I shall try your approach to upgrade them. Thank you for the suggestion.
