Briefly, this error occurs when Elasticsearch expects a single point for geospatial data but receives a list instead. This could be due to incorrect formatting of the input data. To resolve this, ensure that your geospatial data is correctly formatted as a single point, not a list. If you’re using an array, make sure it contains only two elements (longitude and latitude).
