Briefly, this error occurs when the ID field in the Elasticsearch watch contains whitespace, which is not allowed. The watch is a feature that performs actions based on condition fulfillment. To resolve this issue, you should ensure that the ID field does not contain any whitespace. You can do this by either removing the whitespace manually or by implementing a validation check in your application to prevent whitespace in the ID field. Additionally, ensure that the action field is correctly formatted and can be parsed by Elasticsearch.
