playwright integration test with mocked keycloak

[Tockra]

Hi,

I want to run and test my application on localhost:3000. I want to mock all requests against my local keycloak (localhost:8888).
I already found: #867

So I mocked "/openid-configuration", "/token", "/authorize?*".
I used one old jwt token as access_token (I don't know if this works, because the token is not valid anymore.).

export async function mockLogin(page: Page) {
  const configurationResponse = {
    issuer: "http://localhost:8888",
    authorization_endpoint: "http://localhost:8888/authorize",
    token_endpoint: "http://localhost:8888/token",
  };
  await page.route("**/.well-known/openid-configuration", async route => {
    await route.fulfill({
      status: 200,
      body: JSON.stringify(configurationResponse),
    });
  });

  const tokenResponse = {
    access_token: "access_token",
    refresh_token: "refresh_token",
    signature: "signature",
    scope: "refresh_token custom_permissions openid api",
    id_token:

    instance_url: "http://localhost:8888",
    id: "ember_web",
    token_type: "Bearer",
    issued_at: "1687254941736",
  };
  await page.route("**/token", async route => {
    await route.fulfill({ status: 200, body: JSON.stringify(tokenResponse) });
  });

  await page.route("**/authorize?*", route => {
    const url = new URL(route.request().url());
    const state = url.searchParams.get("state");
    route.fulfill({
      status: 302,
      headers: {
        Location: `http://localhost:3000/?code=1234&state=${state}`,
      },
    });
  });
}

But my test fails with error:
