Briefly, this error occurs when the “safety_gap_millis” parameter in Elasticsearch is set to a negative value. This parameter is used to define the safety interval for certain operations and it should always be a non-negative number. To resolve this issue, you should check your Elasticsearch configuration or the specific request where this parameter is set, and ensure that “safety_gap_millis” is set to a valid non-negative value. If it’s not being explicitly set, you may need to investigate why it’s defaulting to a negative value.
