Have this problem for an API feed:
You cannot define a correlation name 'link_attribute_qty_decimal' more than once at public_html/vendor/magento/framework/Webapi/ErrorProcessor.php:208, Zend_Db_Select_Exception(code: 0): You cannot define a correlation name 'link_attribute_qty_decimal' more than once at public_html/vendor/magento/zendframework1/library/Zend/Db/Select.php:833)"}
To me it seems like there is a product with quantity like 10.5 that does not have decimals used in the quantity. Have checked all product and made the changes. But still gets the error.
Anyone that can help me here will be much appreciated :)
