    Description

      Versions:

      • Spring Boot 2.5.6
      • Spring Data Mongo: 3.2.6
      • Mongo Driver: 4.2.3

      I am trying to upgrade my application to latest Spring/Mongo APIs.

      I am getting an error when I try to bulk load data saved using mongoexport.

      Attached is one of the files that gives the error.

      The error is:

      Note that an extra _id is being generated/added by the driver and can be seen in the trace. So the server side error makes sense. I have been tracing through the code but so far haven't found where it gets added.

      This is my code for reference. I am accessing the Mongo driver via the spring template..

         Scanner scanner = new Scanner(is);
          List<InsertOneModel<Document>> documents = new ArrayList<>();
          int count = 0;
       
       
          while (scanner.hasNext()) {
            documents.add(new InsertOneModel<>(Document.parse(scanner.nextLine())));
            count++;
            if (documents.size() > 1000) {
              try {
                template.getCollection(collectionName).bulkWrite(documents,new BulkWriteOptions().bypassDocumentValidation(true).ordered(false));
              } catch (Exception e) {
                System.err.println("Error writing to "+collectionName+ ": "+e.getLocalizedMessage());
              } finally {
                documents.clear();
              }
            }
          }
          try {
              template.getCollection(collectionName).bulkWrite(documents,new BulkWriteOptions().bypassDocumentValidation(true).ordered(false));
          } catch (Exception e) {
              System.err.println("Error writing to "+collectionName+ ": "+e.getLocalizedMessage());
              throw e;
          } finally {
            documents.clear();
          }
          System.out.println(count + " documents loaded for " + collectionName + " collection.");
