Briefly, this error occurs when Elasticsearch fails to update the mapping (schema) for a specific index. This could be due to various reasons such as incorrect mapping syntax, incompatible data types, or insufficient permissions. To resolve this, ensure that your mapping syntax is correct and compatible with your data types. Also, check if the user has the necessary permissions to update the mapping.
