Can't delete index template

Elastic Stack Elasticsearch
1

Using Kibana 8.8.1 and ES 8.8.1 I deleted an index template as follows and it was acknowledged:

DELETE /_index_template/my_template

However, when I run the following the template is still there:

GET /_cat/templates?v

Why is this happening? Thanks.

Could you share the output of the cat template call?

And what's the output of

GET /_index_template/my_template

Sure. I need to clarify that the template I deleted was called 'template_tip'. It was acknowledged. And I can repeat this behavior with other templates. Basically I'm unable to delete a template, or so it seems. Also I see a bunch of dot indices that I don't remember seeing before I upgrading to v8. Can you help understand where those came from?

Sorry you said cat so I misunderstood. I think you want this output:

{
  "error": {
    "root_cause": [
      {
        "type": "resource_not_found_exception",
        "reason": "index template matching [template_tip] not found"
      }
    ],
    "type": "resource_not_found_exception",
    "reason": "index template matching [template_tip] not found"
  },
  "status": 404
}
