Briefly, this error occurs when Elasticsearch is unable to parse a condition for a watch due to a missing or incorrectly formatted field. This is typically caused by a syntax error in the watch definition. To resolve this issue, you should first check the watch definition for any syntax errors or missing fields. Ensure that the field names and values are correctly formatted and that all required fields are present. If the error persists, try to simplify the watch condition to isolate the problematic part. Lastly, ensure that your Elasticsearch version supports the features used in your watch condition.
