Briefly, this error occurs when Elasticsearch is unable to parse a specific action for a watch. This could be due to incorrect syntax, missing fields, or invalid data types in the watch definition. To resolve this issue, you should first verify the syntax of your watch definition. Make sure all required fields are included and that the data types are correct. If the error persists, try to isolate the problematic part by simplifying your watch definition, then gradually add complexity until the error reappears. This will help you identify the exact cause of the problem.

 dynamicNameTimeZone = DateUtils.of(parser.text());
 } else {
 throw new ElasticsearchParseException("could not parse [{}] action for watch [{}]. failed to parse [{}]. must be " +
