Briefly, this error occurs when the geo-coordinates provided to Elasticsearch are not in the correct numeric format. Elasticsearch expects geo-coordinates to be numbers (latitude and longitude). If you provide a string or any other data type, it will throw this error. To resolve this issue, ensure that the geo-coordinates are in the correct numeric format. Also, check your data source to ensure it’s providing the correct data types. If you’re using a script to input data, verify that it’s correctly converting strings to numbers before sending them to Elasticsearch.
