Failed to start elasticsearch when enable CORS

Elastic Stack Elasticsearch

Tried to enable HTTP CORS on ES, but after I added
http.cors.enabled: true
http.cors.allow-origin: "*"
to elasticsearch.yml, ES can't start and I got this error:

Exception in thread "main" SettingsException[Failed to load settings from [elasticsearch.yml]]; nested: ParserException[while parsing a block mapping

      ^

Looks like your configuration file isn't valid YAML. Pay attention to the indentation. If you post the configuration file here we can help you debug it, but make sure you format it as code using the toolbar button.

Here's the problem:

...
# Set a custom port for HTTP:
#
# http.port: 9200
  http.cors.enabled: true
  http.cors.allow-origin: "*"
#
...

Don't indent the http.cors.* lines.

...
# Set a custom port for HTTP:

Yes, exactly. No whitespace at the beginning of the line.
