Briefly, this error occurs when Elasticsearch expects a time unit to be specified in a request, but it is not provided. The time unit could be seconds (s), minutes (m), hours (h), or days (d). To resolve this issue, you should specify the time unit in your request. For example, if you want to set a timeout of 5 seconds, you should write it as “5s”. If you want to set a refresh interval of 1 minute, you should write it as “1m”. Always ensure that the time unit is clearly specified in your Elasticsearch requests.
