I have this issue where I get the following error in the [stage: data migration][step: EAV Step]

In Mysql.php line 110:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')) ORDER BY entity_attribute_id ASC LIMIT 216' at line 1, query was: SELECT eav_entity_attribute.* FROM eav_entity_attribute WHERE (entity_attribute_id >= 0) AND (attribute_id IN ()) ORDER BY entity_attribute_id ASC LIMIT 216

The issue is related to this part "attribute_id IN ()" because the selection is empty. However I do not know where this comes from.

In the map.xml I have both source and destination ignoring the eav document as such


The migration tool is CE to CE from to 2.3.5-p1. No other error appears prior to this step.

I have seen the same issue migrating a store to 2.3.5-p1.

The issue appears to be in the tool at src/Migration/Step/Eav/Data.php Around line 488. I got around it by checking if the attributes are set and not empty.

     * Migrate custom entity attributes
    private function migrateCustomEntityAttributes()
        $sourceDocName = 'eav_entity_attribute';
        $destinationDocument = $this->destination->getDocument(
            $this->map->getDocumentMap($sourceDocName, MapInterface::TYPE_SOURCE)
        $recordsToSave = $destinationDocument->getRecords();
        $customAttributeIds = $this->modelData->getCustomAttributeIds();
        //Added this line
        if(isset($customAttributeIds) && !empty($customAttributeIds)){
            $customEntityAttributes = $this->source->getRecords(
                new \Zend_Db_Expr(sprintf('attribute_id IN (%s)', implode(',', $customAttributeIds)))

        foreach ($customEntityAttributes as $record) {
            $record['sort_order'] = $this->getCustomAttributeSortOrder($record);
            $record['attribute_group_id'] = $this->mapAttributeGroupIdsSourceDest[$record['attribute_group_id']];
            $record['entity_attribute_id'] = null;
            $destinationRecord = $this->factory->create(['document' => $destinationDocument, 'data' => $record]);
        //And this line
        $this->saveRecords($destinationDocument, $recordsToSave);
