Amasty Order Grid

Hi I've installed the new version of Amasty Order Grid but I get this error ‚Äč[2021-07-08 17:19:51] main.CRITICAL: Notice: Array to string conversion in /home/duopticar/web/duoptic.com.ar/public_html/vendor/amasty/ogrid/Model/Indexer/Attribute/Action/DataProvider.php on line 234 {"exception":"[object] (Exception(code: 0): Notice: Array to string conversion in /home/duopticar/web/duoptic.com.ar/public_html/vendor/amasty/ogrid/Model/Indexer/Attribute/Action/DataProvider.php on line 234 at /home/duopticar/web/duoptic.com.ar/public_html/vendor/magento/framework/App/ErrorHandler.php:61)"} [] This error don't let my customers put the orders. I've disabled the module until someone from Amasty check where's the error. I've also downgraded but the issue remains. Thanks in advance!
