I think the answer is actually here github issue - 23411, meaning it is a false positive.
I have created a patch that downgrades the message from 'error' to 'info'. So that visibility is maintained, but severity is downgraded.
file: patches/no_entity_with_customer_id.patch
--- Model/Session.php 2019-11-13 09:59:47.214035581 +0000 +++ Model/Session.php 2019-11-13 10:25:54.187217836 +0000 @@ -274,7 +274,13 @@ $quote = $this->quoteRepository->getActiveForCustomer($customerId); $this->setQuoteId($quote->getId()); } catch (\Magento\Framework\Exception\NoSuchEntityException $e) { - $this->logger->critical($e); + $this->logger->info( + 'Failed to find active quote for customer', + [ + 'customerId' => $customerId, + 'error' => $e->getMessage(), + ] + ); } } else { $quote->setIsCheckoutCart(true);
Then add the following to your patches configuration
"patches": { "magento/module-checkout": { "no such entity with customerId, false positive (https://github.com/magento/magento2/issues/23411#issuecomment-508426676)": "patches/no_entity_with_customer_id.patch" } }
this would require cweagans/composer-patches to be installed.
