invalid type to settype

[decima]

I'm working on implementing an UI for kratos with Symfony and I've got this error using php 8.0.8

ValueError:
settype(): Argument #2 ($type) must be a valid type

Here is my code, maybe i'm doing something wrong:

    /**
     * @Route("/auth/login", name="auth_login")
     */
    public function login(Request $request, Kratos $kratos): Response
    {
        if (!$flowId = $request->query->get("flow")) {
            return $this->redirect($kratos->getBrowserUrl() . "/self-service/login/browser");
        }
        $result = $kratos->admin()->getSelfServiceLoginFlow($flowId, $request->headers->get("cookie"));
        return $this->render('auth/login.html.twig', [
            'ui' => $result->getUi(),
        ]);
    }

Due to new php 8 Consistent type errors for internal functions.
I rewrote my code to be php 7.4.22 compliant, and shutdown the warning :

$result = @$kratos->admin()->getSelfServiceLoginFlow($flowId, $request->headers->get("cookie"));

Is there a solution to use it with php 8.0?

Looks like this is a generator issue - we use openapi generator for generating this repo!

I provided a fix in the generator library as I ran into the same problem. Should be fixed with 5.3.0, the release is due on 18.10.2021.
OpenAPITools/openapi-generator#10576

@aeneasr on 18.10 the generator should be re run with 5.3.0 even without any api changes to fix this problem asap 👍
