[request query.pattern]: expected value of type [string] but got [undefined]

I cannot seem to create an index pattern. There are over 600 fields and I cannot tell which one Kibana has an issue with. I have Kibana logging to stdout. And I can't get a idea of which field it has an issue with. Any thoughts?

Error fetching fields for index pattern (ID: d1d077f0-1993-11ec-9e40-675739437201)

Hi, which version of Kibana is this?

Have you tried looking in our Github repository to see if this is a known issue?

I have found this related issue, which looks like it was closed for not getting enough feedback: https://github.com/elastic/kibana/issues/102512

bash-4.4$ ./kibana --version

As mattkime suggested in Github, please open a new issue for this problem. It will help to give the full information, such as the steps to reproduce: it sounds like you are not using the API to generate these index patterns.

I am afraid I don't know the repro steps. We exposed the hidden indexes in the Kibana UI and we found the two auto-generated indexes via GUID and deleted them. And then the problem went away.
If it pops up again, I will be sure to document it.

Glad that things are working now!

Did your 7.13 cluster have Kibana saved objects that were carried over from a previous version?

Nope, it was a fresh install. However, I did populate data from Filebeat first. Then I swung the data connection from Filebeat to connect to logstash. And then logstash would publish to Elasticsearch.
