Briefly, this error occurs when Elasticsearch expects a numeric value but receives a different data type, such as a string or boolean. This often happens during indexing or querying. To resolve this, ensure that the data type of the field matches the expected numeric type. If the field is dynamically mapped, you may need to explicitly define the mapping. Also, check your queries to ensure they’re not trying to perform numeric operations on non-numeric fields. Lastly, if you’re using scripts, ensure they’re not returning non-numeric values for numeric fields.
