Description

Hi, I am facing a very weird behavior for the code that is generated based on my API, it is working for the most part except that when I make another HTTP call to an external API (e.g. http://localhost:9011) with fetch and then make my Ajax call with the generated code it stucks and when I comment that first http call it does not (this test suit).

Please note that the first http call is taking only a mere 193ms, it is not even a second to get the expected result. So I am completely lost. And that is why I thought of it as a bug and I hope I am not alone on that conclusion.

Generation Details

1. Clone the repo
2. Install deps: npm ci
3. npx nx test:e2e:docker backend-e2e
4. Wait for the configuration and bootstraping app to complete (if for any reason you got an error before tests start to run please reexcute the command)
5. Check you terminal and see the error

Axios/jest should send the request like normal without caring that I am making a separate Ajax call with fetch just how it does work with other test suits. Here is another test suit that passes without any error while making same Ajax call before sending a request with the generated code.

Start with apps/backend-e2e/src/auth/auth-business.e2e-spec.ts around lines 151 and 198, then review the linked openApi.json. Run npx nx test:e2e:docker backend-e2e and compare the passing and timing-out cases, focusing on the fetch call before the generated API request. Done means the refresh-token test completes without the Jest timeout while retaining the external call.
