स्प्रिंग OAuth2UserRequest में पैरामीटर जोड़ने में असमर्थ

मैं क्लाइंट से OAuth2 उपयोगकर्ता सेवा में अतिरिक्त पैरामीटर पास करने में सक्षम होना चाहता हूं। इस स्प्रिंग संदर्भ के बाद https://docs.spring.io/spring-security/site/docs/5.1.1.RELEASE/reference/htmlsingle/#oauth2Client-authorization-request-resolver, मैं जोड़ने में सक्षम हूं OAuth2AuthorizationRequest के लिए अतिरिक्त पैरामीटर। जब मैं अपने कस्टम DefaultOAuth2UserService में पैरामीटर पुनर्प्राप्त करने का प्रयास करता हूं तो यह अब OAuth2UserRequest का हिस्सा नहीं है।

मुझे लगता है कि समस्या OAuth2AuthorizationRequest की समाधान विधि से संबंधित है जिसे दो बार बुलाया जा रहा है, दूसरी बार प्राधिकरण अनुरोध शून्य है। नीचे डिबग लॉग देखें

इस समस्या का निवारण/ठीक करने के बारे में कोई सुझाव?
