I'm using a Magento 2.3.2 in our production site.

But I don't know why when I try to place an order with an existing user, I am getting No such entity with orderId=. When I buy something as a guest, there isn't any problem.

How can I fix it?

no such entity with orderId =

When I check the error in Chrome console, I get the following:

POST http://XXXX/rest/en/V1/carts/mine/payment-information 400 (Bad Request)

  • Try disabling other extensions to see if they are impacting here. Especially the ones with Plugins and Observers for order related classes and events.

  • Hi Nidheesh, I've only one plugin which can be related to orders. Thats the SendCloud plugin, SendCloud is our transport-broker. I’ve disabled and tested but with no positive results. Is it needed to uninstall the extension to test it? Do you have other suggestions? Thanks

For the people who also get this problem, the problem was solved months ago by an external debugger / Magento specialist. The problem was Mageplaza_SameOrderNumber extension. When disabled the order gets successfully created.
