To resolve this issue, you can try the following: 1) Check the format of your data attachment field and ensure it matches the expected format. 2) Verify the data type of your field. If it’s not compatible with the data attachment type, you may need to convert it. 3) Ensure that the Elasticsearch mapper-attachments plugin is properly installed and configured, as it’s responsible for handling data attachments.
