This could be due to incorrect data format, a mismatch between the data type and the field type, or a malformed request. To resolve this issue, you can: 1) Check the data format and ensure it matches the expected format. 2) Verify the field type in your index mapping and ensure it matches the data type. 3) Review the request to ensure it’s correctly formed. 4) If the field is not necessary, consider removing it from the request.
