This is an exception that occurs when there is a conflict between different versions of the same document in Elasticsearch. In this case, the error message indicates that there are two versions of the same document with different sequence numbers (seqNo) and primary terms.
The seqNo is a unique identifier assigned to each update operation performed on a document, while the primary term is used to prevent conflicts between multiple nodes in a distributed cluster. When two updates are performed simultaneously on the same document, Elasticsearch uses the seqNo and primary term to determine which update should be applied first.
In this case, the required seqNo and primary term indicate the version that was expected to be updated, but the current document has a different seqNo and primary term, indicating that it has already been updated by another process. To resolve this conflict, you will need to either retry the update operation or perform a new search to get the latest version of the document before making any changes.
