Solutions

1. Ensure GET /code/image is requested in the same session before login submit.
2. Verify the JSESSIONID cookie is present on both requests.
3. Use a shared session store (Redis) or sticky sessions in clusters.
4. Check session timeout is sufficient.

Example fix

// before
POST /authentication/form  imageCode=ABCD   // no prior GET /code/image -> 不存在

// after
GET  /code/image           // populates session ImageCode
POST /authentication/form  imageCode=ABCD   // same JSESSIONID cookie

// ensure a captcha exists in this session before allowing submit
fetch('/code/image', { credentials: 'same-origin' })
  .then(() => enableLoginForm());

When it happens

Trigger: POST to login with a non-empty imageCode but no ImageCode object in the session - /code/image was not called for this session, or a different session is submitting.

Common situations: JSESSIONID cookie blocked; captcha image endpoint never hit; session expired before submit; clustered deployment without shared sessions; the image captcha was superseded by the SMS flow in testing.
