we are on CE 2.3.6 and have a wired issue with the asyn api. We use the consumer async.operations.all with RabbitMQ as suggested in the manual.
the product with the sku 10914 is successfully generated
the product with the sku 10914 is successfully deleted
Error: The product was unable to be saved. Please try again.
The sequence PUT - DELETE - PUT for the same sku fails.
Products with other sku's can still be generated.
When restarting the queue consumer with "php bin/magento queue:consumers:start async.operations.all" the product in question can again be generated.
Please run the below command and then try to save the products.
rm -rf generated/* php bin/magento indexer:reset php bin/magento indexer:reindex php bin/magento cache:clean
