 SagePaySuiteLogger.Exception: Unique constraint violation found

我正在使用带有表单集成的Ebizmarts Sage付费套件1.2.4和Magento 2.2.3，尽管相信其他版本也有问题。我猜这是一个重复的条目，但是希望有关于这可能是由什么引起或如何修复的任何其他信息。

跟踪：

代码：

这在以下代码中出现：

try {
    if (!$this->isModified($object)) {
        $this->processNotModifiedSave($object);
        $this->commit();
        $object->setHasDataChanges(false);
        return $this;
    }
    $object->validateBeforeSave();
    $object->beforeSave();
    if ($object->isSaveAllowed()) {
        $this->_serializeFields($object);
        $this->_beforeSave($object);
        $this->_checkUnique($object);
        $this->objectRelationProcessor->validateDataIntegrity($this->getMainTable(), $object->getData());
        if ($this->isObjectNotNew($object)) {
            $this->updateObject($object);
        } else {
            $this->saveNewObject($object);
        }
        $this->unserializeFields($object);
        $this->processAfterSaves($object);
    }
    $this->addCommitCallback([$object, 'afterCommitCallback'])->commit();
    $object->setHasDataChanges(false);
} catch (DuplicateException $e) {
    $this->rollBack();
    $object->setHasDataChanges(true);
    throw new AlreadyExistsException(new Phrase('Unique constraint violation found'), $e);
} catch (\Exception $e) {
    $this->rollBack();
    $object->setHasDataChanges(true);
    throw $e;
}

这个错误是什么意思，我怎么能修复/调试我的magento实例，所以这不再发生？
