Briefly, this error occurs when Elasticsearch expects a double value (a number that can have a decimal point), but the provided value is not a valid double. This could be due to incorrect data type or format. To resolve this, ensure that the value you’re inputting is a valid double. This could involve checking your data source for errors, or converting the value to a double before inputting it into Elasticsearch. If the error persists, you may need to check your mapping to ensure the field is correctly set to accept double values.
