Can not reindex after upgrading from 2.3.5 to 2.3.7/8

[srenon]

Preconditions

Magento Version : 2.1.9 EE

ElasticSuite Version : 2.3.7

Environment : Both

Can not longer add or remove a product from category etc because of error in reindexing, after upgrading from Magento 2.1.7EE / ElasticSuite 2.3.5 to Magento 2.1.9EE / ElasticSuite 2.3.8 (or 2.3.7) with same exact product data.

Catalog Search indexer process unknown error:
Notice: Undefined index: status in vendor/smile/elasticsuite/src/module-elasticsuite-catalog/Model/Product/Indexer/Fulltext/Datasource/AttributeData.php on line 51
Product/Target Rule index has been rebuilt successfully in 00:00:00
Target Rule/Product index has been rebuilt successfully in 00:00:00
Sales Rule index has been rebuilt successfully in 00:00:01

##Possible solution
vendor/smile/elasticsuite/src/module-elasticsuite-catalog/Model/Product/Indexer/Fulltext/Datasource/AttributeData.php

        foreach ($childrenIndexData as $childrenId => $childrenData) {
             //check if array key exist
            if(array_key_exists('status', $childrenData)){
                $enabled = current($childrenData['status']) == 1;
                if ($enabled === false) {
                    unset($childrenIndexData[$childrenId]);
                }
            }
        }

Output of print_r($childrenData) in foreach loop

....

    [product_size] => Array
        (
            [0] => 573

    [name] => Array

            [0] => Product 1
        )

)

Array

    [product_size] => Array

        (
            [0] => M
        )

I don't see how it is possible to have products without the status attribute filled.
Maybe a corruption in your data ?

I will try to make the process of indexing more secure but you should check why simple product have no status attribute filled.

Have same issue after migrating from Magento 1.9.3.4 to 2.1.9. Looks like data-migrator tool bug.

[srenon]

@Koc ... we are using a third-party extension to add/update products/attributes but this was build from ground up on Magento 2.x (starting with 2.1.4), so no data-migrator tool was used.

Release 2.3.10 contains the fix.
